HI and CO observations of Arp 104: a spiral-elliptical interacting pair
H. Cullen, P. Alexander, D. A. Green +1
We present data probing the spatial and kinematical distribution of both the atomic (HI) and molecular (CO) gas in NGC 5218, the late-type barred spiral galaxy in the spiral-ellipt…
Giant Metrewave Radio Telescope limits on cool HI in galaxy groups
D. A. Green, M. S. Clemens, P. Alexander +2
We present Giant Metrewave Radio Telescope 21-cm HI observations towards a sample of compact radio sources behind galaxy groups, to search for cool HI. The results -- from high dyn…
The unusual distribution of molecular gas and star formation in Arp 140
H. Cullen, P. Alexander, D. A. Green +2
We investigate the atomic and molecular interstellar medium and star formation of NGC 275, the late-type spiral galaxy in Arp 140, which is interacting with NGC 274, an early-type…
Star Formation in Close Pairs Selected from the Sloan Digital Sky Survey
B. Nikolic, H. Cullen, P. Alexander
The effect of galaxy interactions on star formation has been investigated using Data Release 1 of the Sloan Digital Sky Survey (SDSS). Both the imaging and spectroscopy data produc…
Probing the Physics of Interacting Galaxies
Harriet Cullen, Paul Alexander, Marcel Clemens
Both Arp 140 and Arp 104 reveal extended tidal tails in the HI. The Halpha and FIR fluxes of Arp 140 yield similar SFR of ~0.8 solar masses per year. In contrast the Halpha flux of…
