The connection of the SMBHs to their host galaxies is evidenced by the strong correlation between the mass of SMBH and velocity dispersion, σ, of the stars in rest of
the galaxy. This is somewhat surprising because the ...

Adaptive Optics (AO) technology is a part of ground-based astronomical
observatories around the world. It enables the telescopes to attain near
diffraction-limited resolution. We have designed, developed and tested a ...

Observations of galaxies show that in the nearby universe we see that approximately 2/3 of the
disk galaxies are barred ones (Eskridge et al., 2000). The formation and evolution scenarios
of bars are mainly studied with ...

Magnetic fields are ubiquitous in the universe and play an important role in
variety of astrophysical phenomenon. It is thus very important to understand
the origin, structure and strength of these astrophysical magnetic ...

The thesis, in general aims at studying the early history of the Milkyway through
the chemical abundances of metal poor stars in the Halo and in the satellite galaxies
of the Milkyway. Halo of a galaxy is one of the early ...

The Magellanic Clouds (MCs), neighbouring galaxies to the Milky Way (MW), consist
of a pair of irregular type of galaxies : Large Magellanic Cloud (LMC) and Small Mag-
ellanic Cloud (SMC). The recent proper motion study ...
Datta, A(Indian Institute of Astrophysics, 2017-05)
Solar atmosphere is stratified and exhibits dynamic structures with confined hot plasmas. The corona consists of dynamic magnetic structures, in the form of closed and
open loops with an enhanced plasma density. Moreover, ...

Globular Clusters (GCs) are the systems that contains million of stars bound together
by gravity forming a spherical distribution. As the timescales of dynamical encounters
occurring in these dense systems are shorter ...
Modern astronomical spectrographs have been in use for several hundred
years now, contributing to the study of the physical, chemical and kinematical
properties of stars and other celestial bodies. In the recent years, ...

Single aperture speckle interferometry (Labeyrie, 1970) is a method that de-
ciphers diffraction limited spatial Fourier spectrum and image features of
stellar objects by counteracting blurring effect caused by the ...
Dhar, A(Indian Institute of Astrophysics, 2013-08)
Ultracold atoms is one of the most rapidly expanding fields of modern science. Its ap-
plications are not restricted to just atomic and molecular physics, but also to condensed
matter physics, astrophysics, quantum ...
Bandyopadhyay, A(Indian Institute of Astrophysics, 2019-03)
The thesis aims to study the chemical abundances of very metal poor Milky Way halo
stars and Globular cluster stars, to understand their possible common origin. Halo stars
and globular clusters belong to the oldest stellar ...
Mondal, Chayan(Indian Institute of Astrophysics, 2019-09)
The galaxies in the Universe are changing constantly through secular evolution, mergers
and interactions. Recent star forming activities in galaxies convey important message
about the current evolutionary state of these ...
Gajanan, Deshmukh Prasanna(Indian Institute of Astrophysics, 2019-02)
The next generation large astronomical telescopes are primarily made of
segmented mirrors and construction of such a telescope is a big challenge. It require
enormous amount of works to conceptualize various sub-systems, ...
Indu, G(Indian Institute of Astrophysics, 2014-02)
The Large and Small Magellanic Clouds (LMC & SMC), along with the Magellanic
Bridge and the Stream, comprise the Magellanic system. The presence of the Stream
and the Bridge connecting the two Clouds suggest that these ...
Joby, P. K(Indian Institute of Astrophysics, 2019-01)
The Cosmic Microwave Background (CMB) is the oldest light in the Universe and gives
us access to a picture of the Universe when it was only ≈ 300,000 years old. The CMB
radiation consists of photons free streaming to us ...
Kishore, P(Indian Institute of Astrophysics, 2016-08)
Energetic emission from the Sun can be divided into two broad categories, viz. gradual
and impulsive. It is inferred from white-light observations that the first group is
associated with mass ejections from the solar ...
Mageshwaran, T(Indian Institute of Astrophysics, 2017-11)
A nearly self contained and detailed introduction to TDE physics with novel aspects
and a summary of observations is provided.
We have constructed a dynamical model of tidal disruption events (TDEs) that includes
physical ...
