Discovery of a Remnant Radio Galaxy Using the GMRT
Dr. Dharam Vir Lal, a scientist working at the National Centre for Radio Astrophysics of the Tata
Institute of Fundamental Research (NCRA-TIFR), Pune, India has discovered a remnant radio galaxy
at the peripheral region of a cluster of galaxies named Abell2065, using the upgraded Giant
Metrewave Radio Telescope (uGMRT) and the Chandra X-ray Observatory. The research has been
published in the 16th July 2021 issue of the Astrophysical Journal.
uGMRT uncovers the signature of a cannon ball fired from the Sun, using pulsars!
A group of nearly 20 astronomers, under the banner of Indian Pulsar Timing Array
(InPTA), have for the first time detected the effect of a Coronal Mass Ejection
(CME) from the Sun in the signal from a millisecond pulsar using the upgraded Giant
Metrewave Radio Telescope (uGMRT). This space weather effect on a pulsar from
the Sun is the first of its kind ever reported. This was possible only due to unique
wideband and low frequency capabilities of the uGMRT.
CHIME telescope detects more than 500 mysterious fast radio bursts in its first year of operation
Scientists with the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Collaboration, including researchers at the Tata Institute for Fundamental Research (TIFR) and the National Centre for Radio Astrophysics (NCRA), have assembled the largest collection of fast radio bursts (FRBs) in the telescope’s first FRB catalog, which they will present this week at the American Astronomical Society Meeting.
GMRT measures the atomic hydrogen gas mass in galaxies 9 billion years ago
A team of astronomers from the National Centre for Radio Astrophysics (NCRA-TIFR) in Pune, and the Raman Research Institute (RRI), in Bangalore, has used the Giant Metrewave Radio Telescope (GMRT) to measure the atomic hydrogen gas content of galaxies 9 billion years ago, in the young universe. This is the earliest epoch in the universe for which there is a measurement of the atomic hydrogen content of galaxies. The new result is a crucial confirmation of the group’s earlier result, where they had measured the atomic hydrogen content of galaxies 8 billion years ago, and pushes our understanding of galaxies to even earlier in the universe. The new research has been published in the 2 June 2021 issue of The Astrophysical Journal Letters.
uGMRT reveals for the first time the patchy environment of a rare cosmic explosion
Scientists from the National Centre for radio Astrophysics of the Tata Institute of Fundamental Research (NCRA-TIFR) Pune used the upgraded Giant Metrewave Radio Telescope (uGMRT) to determine that AT 2018 cow, the first of a newly discovered class of cosmic explosions, has an extremely patchy environment.

India joins the global hunt for Gravitational Waves (GW) from monster black holes
A consortium of mainly Indian researchers under the banner “Indian Pulsar Timing Array
(InPTA)”, became a full member of the “International Pulsar Timing Array (IPTA)” , an
international effort to discover and study very low-frequency gravitational waves from
supermassive binary black holes orbiting each other. InPTA regularly employs the upgraded
Giant Metrewave Radio Telescope (uGMRT), situated near Pune to monitor pulsars to obtain
high precision timing measurements. The unique frequency range of the uGMRT, 300 - 800
MHz is not covered by other big telescopes used by IPTA, therefore the inclusion of uGMRT is
crucial in improving the precision of IPTA to detect nano-hertz GWs.
GMRT accorded prestigious IEEE Milestone status
The Giant Metrewave Radio Telescope (GMRT) has achieved yet another honour and major landmark : it has been selected as a IEEE Milestone facility. The Institute of Electrical and Electronics Engineers (IEEE) is the world's largest technical professional organization dedicated to advancing technology in all areas related to electrical and electronics engineering.

Upgraded GMRT measures the atomic hydrogen mass in distant galaxies.
A team of astronomers from the National Centre for Radio Astrophysics (NCRA-TIFR)
in Pune, and the Raman Research Institute (RRI), in Bangalore, has used the
upgraded Giant Metrewave Radio Telescope (GMRT) to measure the atomic hydrogen
content of galaxies seen as they were 8 billion years ago, when the universe was
young. This is the earliest epoch in the universe for which there is a measurement of the
atomic gas content of galaxies.
Indian scientists discover long sought tiny explosions on the Sun
A group of scientists working at the National Centre for Radio Astrophysics (NCRA), Pune have
recently discovered tiny flashes of radio light from all over the Sun. They have identified the
smoking guns for these small magnetic explosions and hence the first ever evidence for their
existence in explaining the long pending coronal heating problem.

A Team of International Scientists including from NCRA discover mildly relativistic outflow from an intriguing transient.
Scientists from the National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research (NCRA-TIFR) were key members of an international team which succeeded in measuring unusually high speed of the ejected material, close to half the speed of light, from a rare class of explosive transient known as Fast Blue Optical Transients (FBOTs).
GMRT discovers a gigantic ring of hydrogen gas around a distant galaxy
A team of astronomers at the National Centre for Radio Astrophysics (NCRA), Pune have discovered a mysterious ring of hydrogen gas around a distant galaxy, using the Giant Metrewave Radio Telescope (GMRT). The ring is much bigger than the galaxy it surrounds, and has diameter about 4 times that of our Milky Way. - January 2020
