We present the photometric catalogs for the star-forming cluster NGC 602 in the wing of the Small Magellanic Cloud covering a range of wavelengths from optical (HST/ACS F555W, F814W, and SMARTS/ANDICAM V, I) to infrared (Spitzer/IRAC 3.6, 4.5, 5.8, and 8 ЮМm and MIPS 24 ЮМm). ... We demonstrate a progression of star formation from the optical star cluster center to the edge of the star-forming dust cloud. ...

Catalogue of Spatially Resolved Kinematics of galaxies . ... The goal of the present project is to built a catalogue gathering references to all spatially resolved studies, for galaxies of all types, whatever the gas or stellar content is concerned. The catalogue has been assembled from merging the lists of Corradi and Capaccioli (1990) and Prugniel and Simien (1996). ... In total, the published catalogue contains 4165 observations of 2070 galaxies referring to 743 published papers. ...

... U. Amsterdam Explanation: The GRB distance scale controversy may have just ended with a flash . Gamma Ray Bursts (GRBs) are powerful explosions occurring in seemingly random positions on the sky. ... There they found a faint but variable optical source : a potential counterpart to the gamma-ray burst that was getting brighter. Most importantly, continued scrutiny showed that this optical transient had absorption lines with a redshift of about 0.8 - the distance scale of galaxies and quasars . ...

Above is a "negative" image of the GRB970508 field , located near the north celestial pole, taken hours after the initial flash of gamma rays. ... About APOD > . ...

Our understanding of star formation in galaxies is facilitated by observations, at multiple wavelengths, of emission which traces stellar populations. ... Using optical integral field spectroscopy, my work aims to better understand the local SFR calibrations, which use H-alpha and radio continuum emission, when applied to different regions of a galaxy, as well as to galaxies as a whole. ...

16th of June 2015 . ASKAP HI imaging of the galaxy group IC 1459 . ... One of these observations was aimed at studying the distribution of neutral hydrogen (HI) gas in the galaxy group IC 1459. ... HI found outside galaxies in this group amounts to at least 10% of the HI contained inside galaxies. This suggests a substantial flow of gas in and out of galaxies during the several billion years of the group's evolution. ... today * ATNF | ... ASKAP | ...

... QSO spectra in the ROSAT band are steeper than the background at harder energies, and furthermore at fluxes below 1E-14 ergs/(s cmќ) the quasar source counts flatten off and are replaced by more numerous populations of relatively low red-shift objects, apparently Narrow Emission Line Galaxies (NELG). ... We extracted the luminosity function from ROSAT Deep Survey results, and extrapolated by a factor of 2 - 3 to account for changes expected in the harder XMM band. ...
