Supernovae (SNe, singular SN), the endpoints of stellar evolution, have fascinated humans since time immemorial, with recorded evidence dating back to two millennia. Continuing this quest, modern astronomy and astrophysics ...
Saraf, Pallavi(Indian Institute of Astrophysics, 2024-11)
The hierarchical mass assembly of galaxies and the formation timescales of their substructures are important topics in astrophysics and cosmology. These aspects can be explored in the local universe by studying resolved ...
Radhika, Dharmadhikari(Indian Institute of Astrophysics, 2024)
The segmented mirror technology has become the preferred choice for building moderate to large-size optical telescopes. For the segmented primary mirror to function like a single monolithic mirror, each segment must be ...

Exploration of the transient Universe is an exciting and fast-emerging area within radio astronomy. Radio transient sources can be defined as a class of objects that emit radio waves in the form of bursts, flares, or pulses ...
Khan, Raveena(Indian Institute of Astrophysics, 2024)
Magnetic fields are the primary driver of the plasma thermodynamics in the upper solar atmosphere, especially in the transition region (TR) and the corona. These magnetic fields hold the key to long standing questions in ...
Saha, Piyali(Indian Institute of Astrophysics, 2021)
Star formation is a chain of processes in which molecular clouds get converted to a compact stellar systems, which are the potential platforms of life. Although, numerous observations and simulations have been performed ...
Mathur, Harsh(Indian Institute of Astrophysics, 2024)
The chromosphere, situated between the bright photosphere and the remarkably thin transition region that precedes the million-degrees hot corona, is a highly dynamic and intricate layer within the solar atmosphere. By ...
Saraswathi Kalyani, S(Indian Institute of Astrophysics, 2024)
Ground-based telescopes are severely limited in their performance by the turbulence of the Earth’s atmosphere. The wavefronts emitted by the celestial bodies are perturbed and we lose high spatial frequency information. ...
Swastik, C(Indian Institute of Astrophysics, 2024-03)
Numerous groundbreaking discoveries have been made in exoplanet science over the
past decade. Recent exoplanet search surveys have provided compelling evidence that
planets are exceedingly common, with the majority of ...
Ansar, Sioree(Indian Institute of Astrophysics, 2024-03)
Investigating stellar structures such as stellar bars within the central regions of galaxies
holds promise as a means to examine the properties of dark matter halos associated
with those galaxies. Cosmological simulations ...
Singla, Manika(Indian Institute of Astrophysics, 2023-04)
Context: Over 5,000 exoplanets have been discovered to date, yet our
knowledge of their atmospheres is still quite limited, and we have not yet
identified any truly habitable exoplanets. It is the high time to characterize
the ...
Prabhakar, Maya(Indian Institute of Astrophysics, 2023-03)
The outer solar atmosphere, the corona, is known for its million-degree temperature. The mystery
surrounding the source of this high temperature is gradually being resolved with various theories,
observations and models. ...
Deepthi, S. Prabhu(Indian Institute of Astrophysics, 2023-07)
Galactic Globular clusters (GGCs) are old stellar systems (age ∼ 12 Gyr) consisting
typically of about 104-106 gravitationally bound stars. This makes them excellent
astrophysical laboratories to study stellar evolution, ...
Sharma, Ravi Kumar(Indian Institute of Astrophysics, 2023-11)
The ΛCDM model is the most successful model of cosmology to fit most of the cosmological observations, yet a few discrepancies exist. There is a 4σ to 5σ mismatch in determining the Universe’s current expansion rate from ...
Yadav, Jyoti(Indian Institute of Astrophysics, 2023-05)
The cold gas accretion and merging of galaxies are two important physical mechanisms which contribute to the building up of galaxies at various epochs of the universe. Thus, it is crucial to understand the role of gas ...
Fazlu, Rahman(Indian Institute of Astrophysics, 2023-08)
Accurate component separation of full-sky maps in the radio and microwave frequencies, such as the cosmic microwave background (CMB), relies on a thorough understanding of the statistical properties of the Galactic foreground ...
Pal, Indrani(Indian Institute of Astrophysics, 2023-05)
Active Galactic Nuclei (AGN), amongst the most luminous sources in the Universe (L = 1042 − 1046 erg s −1 ), emit radiation over the entire electromagnetic band. Though AGN are known to be powered by the accretion of matter ...
