K. ; Papovich, C. | American Astronomical Society | 2008-03-01We present Spitzer IRS mid-infrared spectra for 15 gravitationally lensed, 24 ?m-selected galaxies, and combine the results with four additional very faint galaxies with IRS spectra in the literature. The median intrinsic 24 ?m flux density of t[...]![]()

Ultraviolet (UV) nonionizing continuum and mid-infrared (IR) emission constitute the basis of two widely used star formation (SF) indicators at intermediate and high redshifts. We study 2430 galaxies with z![]()

The cold molecular gas in contemporary galaxies is structured in discrete cloud complexes. These giant molecular clouds (GMCs), with 10^(4) –10^(7) solar masses (M?) and radii of 5–100 parsecs, are the seeds of star formation1 . Highlighting the[...]![]()

Relaño, M. ; Lisenfeld, U. ; Pérez González, Pablo Guillermo ; Vílchez, J. M. ; Battaner, E., E. | American Astronomical Society | 2007-10-01We investigate the use of the rest-frame 24 ?m luminosity as an indicator of the star formation rate (SFR) in galaxies with different metallicities by comparing it to the (extinction-corrected) H? luminosity. We carry out this analysis in two s[...]![]()

The galaxy number counts has been traditionally used to test models of galaxy evolution. However, the origin of significant differences in the shape of number counts at different wavelengths is still unclear. By relating the most remark[...]![]()

We investigate the galaxy quenching process at intermediate redshift using a sample of similar to 4400 galaxies with M-* > 10(9) M-circle dot between redshift 0.5 and 1.0 in all five CANDELS fields. We divide this sample, using the integrated sp[...]![]()
