Two long HI tails in the outskirts of Abell 1367
T. C. Scott, L. Cortese, E. Brinks +3
We present VLA D-array HI observations of the RSCG42 and FGC1287 galaxy groups, in the outskirts of the Abell 1367 cluster. These groups are projected ~ 1.8 and 2.7 Mpc west from t…
VII Zw 403: HI Structure in a Blue Compact Dwarf Galaxy
Caroline E. Simpson, Deidre A. Hunter, Tyler E. Nordgren +9
We present optical (UBVJ), ultraviolet (FUV, NUV), and high resolution atomic hydrogen (HI) observations of the nearby blue compact dwarf (BCD), VII Zw 403. We find that VII Zw 403…
Studying the spatially resolved Schmidt-Kennicutt law in interacting galaxies: the case of Arp 158
Médéric Boquien, Ute Lisenfeld, Pierre-Alain Duc +4
Recent studies have shown that star formation in mergers does not seem to follow the same Schmidt-Kennicutt (KS) relation as in spiral disks, presenting a higher star formation rat…
HI asymmetries in the isolated galaxy CIG 292
António Portas, Tom C. Scott, Elias Brinks +9
We present Expanded Very Large Array (EVLA) D-array observations in the 21-cm line of neutral hydrogen (HI) of CIG 292, an isolated SA(s)b galaxy at a distance of ~ 24.3Mpc. From p…
A Molecular Star Formation Law in the Atomic Gas Dominated Regime in Nearby Galaxies
Andreas Schruba, Adam K. Leroy, Fabian Walter +11
We use the IRAM HERACLES survey to study CO emission from 33 nearby spiral galaxies down to very low intensities. Using atomic hydrogen (HI) data, mostly from THINGS, we predict th…
Theoretical determination of HI vertical scale heights in the dwarf galaxies: DDO 154, HoII, IC2574 & NGC2366
Arunima Banerjee, Chanda J. Jog, Elias Brinks +1
In this paper, we model dwarf galaxies as a two-component system of gravitationally coupled stars and atomic hydrogen gas in the external force field of a pseudo-isothermal dark ma…
