AstroSat-UVIT observations of a possibly interacting pair of galaxies in HCG 77
Astronomy & AstrophysicsContext. Interactions and mergers possibly enhance the star formation in dwarf galaxies in a group environment. Aims. We aim to study star-forming regions and the spectral energy distribution of two possibly interacting galaxies, PGC 56121 and PGC 56125,

Optical polarimetry studies of Seyfert galaxies [PDF]
, 1999 Optical imaging polarimetry has been performed on seven nearby Seyfert galaxies, three with face-on and four with edge-on host galaxies of various morphological classifications.

Interacting galaxies: corotating and counter-rotating systems with tidal tails [PDF]
, 2013 We analyse interacting galaxy pairs with evidence of tidal features in the Sloan Digital Sky Survey Data Release 7. The pairs were selected within z< 0.1 by requiring a projected separa- tion rp < 50 h −1 kpc and relative radial velocityV < 500 km s −1 .

Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]
, 2005 Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

Star formation and agn activity in interacting galaxies : A near-UV perspective [PDF]
, 2013 We study nearby galaxies in close pairs to study the key factors affecting star formation and AGN activity triggered during galaxy interactions. Close pairs are selected from the Sloan Digital Sky Survey assuming a projected separation of $

Are Disks of Satellites Comprised of Tidal Dwarf Galaxies?
Galaxies, 2021 It was found that satellites of nearby galaxies can form flattened co-rotating structures called disks of satellites or planes of satellites. Their existence is not expected by the current galaxy formation simulations in the standard dark matter-based ...
