The dependence of HII region properties on global and local surface brightness within galaxy discs
J. F. Helmboldt, R. A. M. Walterbos, G. D. Bothun +2
Using B, R, and H-alpha images of roughly equal-sized samples of low surface brightness (LSB) and high surface brightness (HSB) galaxies (~40 galaxies apiece), we have explored the…
The Arecibo Galaxy Environment Survey: II. A HI view of the Abell cluster 1367 and its outskirts
L. Cortese, R. F. Minchin, R. R. Auld +13
We present 21 cm HI line observations of 5x1 square degrees centered on the local Abell cluster 1367 obtained as part of the Arecibo Galaxy Environment Survey. One hundred sources…
Strangers in the night: Discovery of a dwarf spheroidal galaxy on its first Local Group infall
S. C. Chapman, J. Penarrubia, R. Ibata +9
We present spectroscopic observations of the AndXII dwarf spheroidal galaxy using DEIMOS/Keck-II, showing it to be moving rapidly through the Local Group (-556 km/s heliocentric ve…
Star Formation in Galaxies with Large Lower Surface Brightness Disks
K. O'Neil, S. Oey, G. Bothun
We present B, R, and Halpha imaging data of 19 large disk galaxies whose properties are intermediate between classical low surface brightness galaxies and ordinary high surface bri…
G515, Revisited. I. Stellar Populations And Evidence Of Nuclear Activity In A Luminous "E+A" Galaxy
Charles T. Liu, Eric J. Hooper, Karen O'Neil +3
We present multiwavelength observations of the very luminous "E+A" galaxy known as G515 (J152426.55+080906.7), including deep K_s imaging, spatially resolved H-alpha spectroscopy,…
The Arecibo Galaxy Environment Survey: Precursor Observations of the NGC 628 group
R. Auld, R. F. Minchin, J. I. Davies +25
The Arecibo Galaxy Environment Survey (AGES) is one of several HI surveys utilising the new Arecibo L-band Feed Array (ALFA) fitted to the 305m radio telescope at Arecibo. The surv…
