IUCAA invites applications to participate in the
Junior Research Fellow (JRF) [ 2023 ]
Project Name: Designing, fabrication, and characterisation of a complete Extended Cavity Diode Laser (ECDL) system
LIGO-India detector will require frequency-stabilised input lasers. The present LIGO detectors in the USA operate at 1064 nm wavelength, which is likely to be changed to 1500 nm or 2-micron wavelengths in future upgrades. Keeping that in mind, we plan to indigenise the Extended Cavity Diode Laser System: which incorporates opto-mechanical assembly of the ECDL, its drivers, and master control. We plan to design the opto-mechanical system, electronic hardware, and control system as wavelength independent such that we can use it for any laser diode wavelengths for its specific package(s). For that purpose, IUCAA is looking for a highly motivated JRF candidate with basic knowledge in atomic physics, laser physics, geometrical optics, and electronics. Hands-on experience in instrumentation will be useful.
Qualification:
M. Sc. or M. Tech in Physics/ Electronics/ Instrumentation/ Optical engineering/ other related areas with minimum 60% marks. Candidates having NET-JRF / NET-LS/ GATE/ INAT/ JEST will be preferred. Final-year students waiting for results can also apply.
Remuneration:
The positions offer a monthly fellowship and other facilities given to Junior Research Fellows as per standard norms.
Tenure:
The total tenure of the position is for 3 years or till the availability of funds, whichever comes first, and is renewable annually based on performance.
General Information: IUCAA will not be responsible for the candidate's accommodation.
Project Start Date: The selected candidate can start to work immediately after the selection on a mutually agreeable date.
Last Date to Apply: June 28, 2023
Last Date to Submit Referee Report: June 30, 2023
For any further query or discussion about the project, interested candidates may feel free to contact Prof. Subhadeep De [ subhadeep@iucaa.in ], the principal investigator of this project.

Project Name: Search and parameter estimation of gravitational-wave signals
Gravitational-wave (GW) data analysis includes detection of GW signals from the data obtained at the observatories. This project will focus on the successful deployment of all the search and the parameter estimation pipelines currently used by the LIGO-Virgo-KAGRA (LVK) collaboration for gravitational-wave (GW) searches and astrophysics. The search pipelines will include filtering data with waveform templates of merging black holes and neutron stars as well as generic search for GW transients with minimal assumption of the source and signal morphology. Search for periodic GW signatures from rotating neutron stars and GW background of cosmological or astrophysical origin are of utmost importance.
The pipelines need to run on the IUCAA LIGO Data Grid cluster, Sarathi, using publicly available GW data. The selected candidate will need to coordinate with the LVK experts of the various pipelines as well as the system administrators of Sarathi. A strong computational background with experience in programming languages like Python, C, C++ and familiarity in GW data analysis will be preferred.
Qualification:
M. Sc. or B. Tech. in Physics/ Computer Science or any other related areas with minimum 60% marks. Candidates having NET-JRF / NET-LS/ GATE/ INAT/ JEST will be preferred. Final-year students waiting for results can also apply.

Project Name: Detector characterisation
Detections of gravitational waves very much depend on the sensitivity of the instrument, how long the detectors can stay online without major interruptions, well-understood noise properties, accurate calibration of the data and so on. This is enabled by Detector characterisation which is a major and crucial activity of the LVK collaboration. It involves tasks such as sharing the data quality information in order to avoid/exclude bad data, veto false positives and enable candidate follow-up for gravitational wave searches. Additional tasks include validating the quality of the data around the time of candidate gravitational wave event detections. Many specialised software and infrastructure has been developed to facilitate detector characterisation. For example, iDQ, GW-DetChar, GWSumm, HVeto, UPV and Gravity Spy.
The selected JRF is expected to get acquainted with existing detector characterisation pipelines in the LIGO collaboration, interact with collaboration members on a regular basis and gain expertise to test and run these pipelines in the cluster at IUCAA. The selected JRF will also be required to disseminate and impart the experience thus gained in the form of Python tutorials, documentation, etc. Furthermore, there will be opportunities to develop and/or improve existing pipelines which may include closely working with teams with specific astrophysical goals. This expertise will be necessary for LIGO-India operations.
It is not expected that the candidate shall have prior expertise in aforementioned areas other than basic knowledge in Physics and Computer Programming. It is desirable though for the candidate to have demonstrable experience in Python code development and web programming.

M. Sc. or B. Tech. in Physics/ Computer Science or any other related areas with minimum 60% marks. Candidates having NET-JRF / NET-LS/ GATE/ INAT/ JEST will be preferred. Final-year students waiting for results can also apply.

Project Name: Seismic Isolation in Gravitational Wave detectors
Extending the sensitivity of the gravitational wave detectors in the low frequency regime is one of the areas of research being actively pursued at IUCAA as well as globally within the LIGO Scientific Collaboration. Our goal is to develop novel isolator designs, seismic sensors, actuators, advanced signal and data processing techniques and control system architectures to improve the attenuation of ground motion effects on suspended optics. The work is highly multidisciplinary, spanning mechanical engineering, electronics and communication engineering, data analysis, instrumentation and control systems in addition to basic physics of high precision measurements. Applicants with a strong background in experimental physics and electro-mechanical engineering are encouraged to apply. The selected candidate would have the opportunity to work with the global gravitational wave community in this domain.
