AstroSat-UVIT observations of a possibly interacting pair of galaxies in HCG 77
Anshul Srivastava, Harvinder K. Jassal, Mamta Gulati +1
We aim to study star-forming regions and the spectral energy distribution of two possibly interacting galaxies, PGC 56121 and PGC 56125, in the Hickson Compact Group 77. We utilize…
Semi-analytical model for the calculation of solar radiation pressure and its effects on a LEO satellite with predicting the change in position vectors using machine learning techniques
Pranava Seth, Mamta Gulati
The rapid increase in the deployment of Low Earth Orbit (LEO) satellites, catering to diverse applications such as communication, Earth observation, environmental monitoring, and s…
Status of Astronomy Education in India: A Baseline Survey
Moupiya Maji, Surhud More, Aniket Sule +28
We present the results of a nation-wide baseline survey, conducted by us, for the status of Astronomy education among secondary school students in India. The survey was administere…
Study of dependence of ram pressure stripping on the orbital parameters of the galaxies
Ankit Singh, Shreya Davessar, Mamta Gulati +2
Comprehensive observations of galaxy clusters suggest that gas deficiency in the galaxies could be due to ram pressure stripping due to the high-pressure intra-cluster medium actin…
RAD@home citizen science discovery of an AGN spewing a large unipolar radio bubble onto its merging companion galaxy
Ananda Hota, Pratik Dabhade, Sravani Vaddi +8
AGN feedback during galaxy merger has been the most favoured model to explain black hole-galaxy co-evolution. However, how the AGN-driven jet/wind/radiation is coupled with the gas…
Ram pressure stripping: An analytical approach
Ankit Singh, Mamta Gulati, J. S. Bagla
We use an analytical approach to study ram pressure stripping with simple models for discs and halo gas distribution to study the phenomena in cluster, group and galaxy halos. We a…
Modal analysis of gravitational instabilities in nearly Keplerian, counter-rotating collisionless discs
Mamta Gulati, Tarun Deep Saini
We present a modal analysis of instabilities of counter-rotating, self-gravitating collisionless stellar discs, using the recently introduced modified WKB formulation of spiral den…
A modified WKB formulation for linear eigenmodes of a collisionless self-gravitating disc in the epicyclic approximation
Mamta Gulati, Tarun Deep Saini
The short--wave asymptotics (WKB) of spiral density waves in self-gravitating stellar discs is well suited for the study of the dynamics of tightly--wound wavepackets. But the text…
Unstable modes of counter-rotating Keplerian discs
Mamta Gulati, Tarun Deep Saini, S. Sridhar
We study the linear counter-rotating instability in a two-component, nearly Keplerian disc. Our goal is to understand these \emph{slow} modes in discs orbiting massive black…
Slow pressure modes in thin accretion discs
Tarun Deep Saini, Mamta Gulati, S. Sridhar
Thin accretion discs around massive compact objects can support slow pressure modes of oscillations in the linear regime that have azimuthal wavenumber . We consider finite, f…
