Project Post-doctoral Positions

(1) Developing narrow line-width ultra-stable laser for quantum metrology

Looking for a motivated post-doctoral fellow (PDF) to work in the Precision & Quantum Measurement Lab (PQM-lab) that aims to develop quantum enhanced technologies to support national missions on quantum computation & communication as well as to pursue precision atomic spectroscopy for probing fundamental sciences such as geodesy, probing possible breaking of fundamental symmetries or violations of the fundamental constants and so on. The experiment at the PQM-lab shall comprise of a trapped ytterbium-ion (Yb+) optical clock for absolute optical referencing, ultra-stable Fabry-Perot (FP) cavity, stabilized optical frequency comb to generate photons at the desired wavelengths and phase stabilized link-fiber. For that purpose, we are looking for PDF with hands on experimental experience in the areas of lasers & optics, vacuum technologies, electronics instrumentation together with knowledge in Matlab/Mathematica, LabVIEW, Python/C++, CAD and so on.

(2) Gravitational-wave astrophysics

Applications are invited from researchers with outstanding track record in (a) gravitational wave data analysis or detector characterization, (b) numerical relativity, (c) relativistic astrophysics, or a closely related research area, for a postdoctoral position in Prof. Sukanta Bose's group beginning in fall 2021.

IUCAA is a lead institution in the LIGO-India project. Financial support for attending international and national meetings and collaborative visits is available. Information on gravitational-wave research being pursued in IUCAA can be found at:

(3) High-redshift galaxies

The fraction of escaping Lyman continuum photons plays a crucial role in the early galaxy formation. Currently, there are only a handful of galaxies that are known to be leaking such photons. The Ultraviolet Imaging Telescope onboard AstroSat is promising in this regard.

The primary goal of this project is to model high-redshift galaxies that are leaking Lyman continuum radiation.

The successful candidate will have the chance to work with the AstroSat Uv Deep Field (AUDF) and multi-wavelength dataset available from HST, Spitzer, and ground-based observations from 8m class telescopes such as VLT/ESO. Preference will be given to candidates with knowledge of photometry and spectroscopy and a basic understanding of Astronomical software such as IRAF and python coding.

(4) 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.

(5) 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:

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

For MALS postdoctoral fellowship, we are looking for candidates with experience in observational astronomy. Demonstrated expertise in radio 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 (i) automated processing of MALS data to generate science-ready continuum images and spectral line cubes, and (ii) automated source finding to generate catalogs. The infrastructure for automated processing of data from the initial phases of the survey is in place. 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.

(6) Multi-Wavelength Study of Solar Atmosphere

The successful candidate will primarily study the dynamic coupling of the solar atmosphere using the observations recorded by space missions such as the Interface Region Imaging Spectrometer (IRIS), Hinode, and the Solar Dynamics Observatory (SDO) to study the dynamic coupling of the solar atmosphere. These observations shall be coupled with 0D and 1D hydrodynamical simulations. Experience in spectroscopy will be an advantage.

These studies will lead to the development of science objectives for the Solar Ultraviolet Imaging Telescope (SUIT) on board the upcoming Aditya-L1 mission. SUIT will observe the Sun within 200-400 nm (basically covering the photosphere and chromosphere) with the primary aim of proving better understanding of the coupling of lower solar atmosphere and for the firs time measuring the spatially resolved solar spectral irradiance in the wavelength range that is crucial for sun-climate relations.
