Using new UV magnitudes for a sample of early-type galaxies (ETGs) with published stellar mass-to-light ratios, ?_*, we find a correlation between UV color and ?_* that is tighter than those previously identified between ?_* and either the centr[...]texto impreso

K. ; Meyer, Jennifer Donovan ; Gil de Paz, Armando ; Imanishi, Masatoshi ; Madore, Barry F. ; Thilker, David A. | IOP Publishing | 2015-04-01We report the discovery of a new dwarf galaxy (NGC 6503-d1) during the Subaru extended ultraviolet disk survey. It is a likely companion of the spiral galaxy NGC 6503. The resolved images, in the B, V, R, i, and H alpha bands, show an irregular [...]texto impreso
Dullo, Bililign T. ; Bouquin, Alexandre Y. K. ; Gil de Paz, Armando ; Knapen, Johan H. ; Gorgas García, Francisco Javier | IOP publishing ltd | 2020-07Tight correlations between supermassive black hole (SMBH) mass (M_(BH)) and the properties of the host galaxy have useful implications for our understanding of the growth of SMBHs and evolution of galaxies. Here, we present newly observed correl[...]texto impreso
We extend our initial study of the connection between the UV colour of galaxies and both the inferred stellar mass-to-light ratio, Upsilon(*), and a mass-to-light ratio referenced to Salpeter initial mass function (IMF) models of the same age an[...]texto impreso

We find a very tight. GALEX blue sequence (GBS) in the (FUV- NUV) versus (NUV-[3.6]) color- color diagram, which is pop[...]texto impreso
The Spitzer Survey of Stellar Structure in Galaxies is a volume, magnitude, and size-limited survey of 2352 nearby galaxies with deep imaging at 3.6 and 4.5 ?m. In this paper, we describe our surface photometry pipeline and showcase the associat[...]
