HI Imaging of a Blueberry Galaxy Suggests a Merger Origin
Saili Dutta, Apurba Bera, Omkar Bait +3
Blueberry galaxies (BBs) are fainter, less massive, and lower redshift counterparts of the Green pea galaxies. They are thought to be the nearest analogues of the high redshift Lym…
Bending Waves in Velocity Space: a First Look at the THINGS sample
Meera Nandakumar, Chaitra Narayan, Prasun Dutta
Detection of bending waves is a highly challenging task even in nearby disc galaxies due to their sub-kpc bending amplitudes. However, simulations show that the harmonic bending of…
The central region of the enigmatic Malin 1
Kanak Saha, Suraj Dhiwar, Sudhanshu Barway +2
Malin 1, being a class of giant low surface galaxies, continues to surprise us even today. The HST/F814W observation has shown that the central region of Malin 1 is more like a nor…
Wobbly discs -- corrugations seen in the dust lanes of edge-on galaxies
Chaitra A. Narayan, Ralf-Juergen Dettmar, Kanak Saha
We report the detection of small scale bending waves, also known as corrugations, in the dust lanes of five nearby edge-on disc galaxies. This phenomenon, where the disc mid-plane…
The extended Planetary Nebula Spectrograph (ePN.S) early-type galaxy survey. The kinematic diversity of stellar halos and the relation between halo transition scale and stellar mass
C. Pulsoni, O. Gerhard, M. Arnaboldi +14
In the hierarchical two-phase formation scenario, the extended halos of early type galaxies (ETGs) are expected to have different physical properties from those of the galaxies' ce…
The thickness of HI in galactic discs under MOND: theory and application to the Galaxy
F. J. Sanchez-Salcedo, K. Saha, C. A. Narayan
The outskirts of galaxies are a very good laboratory for testing the nature of the gravitational field at low accelerations. By assuming that the neutral hydrogen gas is in hydrost…
