Project Post-doctoral Positions


(1) Developing low-noise electronic hardware for driving the ion-traps

The Precision & Quantum Measurement laboratory (PQM-lab: https://pqmlab.iucaa.in/) at IUCAA is developing a trapped-ion based precision experiment, which require multi-discipline expertise. We are looking for a highly motivated post-doctoral fellow (PDF) who can work and must fully engage himself/ herself to develop the PQM-lab experiment in a collaborative manner. One of the critical requirements is sophisticated high-end (i.e., low-noise, fast operating, and compact) electronic hardware to drive the ion-traps. The planned chip scale trap shall consist array of microfabricated ion-traps, which need to use phase-coherent radio-frequency (RF) to the individual electrodes; their fast switching for coherent manipulation and shuttling of the ions. Worldwide, state-of-the-art chip scale ion traps use field programmable gate array (FPGA) based technology for that purpose, however, generating the phase coherent & stable RFs at the desired level is yet an open challenge. PQM-lab is intending to hire a post-doctoral fellow who will be interested to develop the adequate electronic hardware to fill the gap. For that hands-on expertise in embedded system, Verilog, FPGA technology, microprocessor, digital signal processing with high level knowledge in electronics (analog, digital and RF) will be desired. Candidates who pursued PhD in experimental Physics, instrumentation, any branches of engineering, however have ample of expertise in the above-mentioned areas of electronics and keen to work are favorable.

(2) Developing optical sub-systems for the ytterbium-ion experiment

The Precision & Quantum Measurement laboratory (PQM-lab: https://pqmlab.iucaa.in/) at IUCAA is developing a trapped-ion based precision experiment, which require multi-discipline expertise. We are looking for a highly motivated post-doctoral fellow (PDF) who can work and must fully engage himself/ herself to develop the PQM-lab experiment in a collaborative manner.The second scope is, developing the elaborate optical setup for photo-ionization, laser cooling and probing the clock transition of ytterbium-ion experiment. This require simultaneous use of the five lasers at different wavelengths and each of the lasers need to operate at multiple frequencies to address the hyperfine sublevels. For long-term robust and stable operations, each of the lasers have to frequency & power stabilized. The candidate is expected to design and develop the suitable optical assemblies and need to transport these lights to the experiment in an efficient manner (fiber or free-space). For that hands-on expertise in optics, opto-mechanics, PID & lock-in electronics, designing optical systems will be essential. Candidates who pursued PhD in experimental Physics, instrumentation and have expertise in the above-mentioned areas are favorable.

(3) MHD simulations of high energy astrophysical phenomenon

We would like to invite applications for a postdoctoral position in the research group of Prof. Dipanjan Mukherjee. Depending on the candidate's expertise, they can choose to work on any one of the following broad topics:
1: MHD simulations of supernovae driven turbulence: The project will involve setting up a new supernova driving module in the PLUTO code. The goal will be to characterise the dependence of the turbulent properties of the ISM for a range of physical properties of the medium and supernova rate, and predict observables for different emission processes.
2: Simulating accretion on neutron stars: Simulations are to be performed to model the accretion flow on neutron stars. The simulations will test the accretion flow properties at different heights from the surface and the effects of different physical processes such as MHD instabilities and radiation pressure.
3: AGN feedback in low-mass galaxies: Simulations of feedback (both mechanical and radiative) are to be performed to test the efficiency of AGNs in low mass galaxies in clearing out the star-forming gas.
Candidates with exposure to MHD simulations, numerical techniques and expertise in coding will be favoured.

(4) MeerKAT Absorption Line Survey (MALS)

The MeerKAT Absorption Line Survey (MALS; PIs: N. Gupta and R. Srianand) is one of the ten large surveys to be carried out with the MeerKAT radio telescope in South Africa. The MeerKAT array consists of 64 dishes with 13.5m dishes, designed to achieve high sensitivity and imaging dynamic range. The MALS is allocated 1655 hrs of MeerKAT time to carry out the most sensitive search of HI and OH absorption lines at 0<z<2, the redshift range over which most of the evolution in the star formation rate density takes place. The key science themes of the survey are: (1) Evolution of atomic and molecular gas in galaxies and relationship with star formation rate density, (2) Fuelling of active galactic nucleus (AGN), AGN feedback and dust-obscured AGNs, (3) Variation of fundamental constants of physics, (4) Evolution of magnetic fields in galaxies, and (5) Physical modeling of the ISM, Astrochemistry and Cosmology. Due to the excellent sensitivity of the MeerKAT telescope, MALS will also deliver an extremely sensitive HI 21-cm emission, radio continuum and polarization survey to address a wide range of issues at the forefront of galaxy evolution research. The detailed survey design and current status are available at: http://mals.iucaa.in.

The MALS L-band observations started on June 14, 2020 and about 400 hrs of data have been acquired. These datasets are already available to pursue various science projects. The UHF-band phase is expected to start later this year.

For MALS postdoctoral fellowship, we are looking for candidates with experience in observational astronomy. Demonstrated expertise in radio/optical/IR astronomy techniques and experience in programming languages such as C/C++ and Python are highly desirable. The main responsibility of the successful candidate will be to work closely with the MALS team on either of (i) automated processing of MALS data to generate science-ready continuum images and spectral line cubes, and (ii) automated source finding to generate catalogs and (iii) planning and analysing followup optical imaging and spectroscopic observations. The infrastructure for automated processing of data from the initial phases of the survey is in place. Optical observations with NTT/SALT/NOT and other facilities are underway. The candidate will use these and also participate in the development of new tools and techniques required for the project. It is expected that the candidate will utilize this opportunity to develop and lead research projects based on MALS datasets.

(5) The evolution of groups and clusters of galaxies

Applications are invited for a post-doctoral position to work with Professor Somak Raychaudhury on the evolution of groups and clusters of galaxies.

Galaxies in groups and clusters evolve through close interaction with each other, and with the cluster environment, in particular the intergalactic medium and dark matter halo. Groups and clusters in turn evolve through mergers, giving rise to interesting observational effects that can be studied through multi-wavelength observations, particularly in radio continuum and X-rays. We are looking for a postdoctoral fellow who will work with us in studying the formation and evolution of groups and clusters, their interaction with the large-scale structure, and the evolution of galaxies within them.

Requisites: Candidates who have submitted their Ph.D. thesis, or have been granted the Ph.D. degree, in Physics, Astronomy, or other related fields can apply. They must have experience in reducing and interpreting radio, X-ray or optical/UV data on galaxies, groups or clusters, or have conducted cosmological simulations involving galaxies, clusters or dark matter.

(6) IUCAA Rubin LSST

IUCAA is an international contributor for the Vera Rubin Observatory's Legacy Survey of Space and Time, an ambitious program to conduct a 10-year multiband imaging survey using a 6.5m class wide field telescope. The LSST will deliver a large database of images and derived data products which can address a variety of questions about the transient as well as the static Universe. The Rubin LSST science collaborations include the Dark Energy Science Collaboration, the Transient and Variable Stars Science Collaboration, the Galaxies Science Collaboration and the Strong Lensing Science Collaboration. IUCAA would like to hire a postdoctoral scholar to be embedded within one of these collaborations under the supervision of IUCAA Rubin LSST Principal investigators.

The successful candidate would obtain data rights to proprietary LSST data for the 2 year duration of the position and would carry out infrastructure work for these science collaborations in an area related to her/his expertise. Although a significant percentage (at least 50 percent) of the effort of the postdoctoral scholar will be directable by Rubin LSST, there will be ample opportunity for independent research work. Research experience in any of the areas of interest to the science collaboration is expected. Software carpentry skills are essential, and familiarity with the use of software repositories will be an added advantage.
