The bolometric and UV attenuation in normal spiral galaxies of the Herschel Reference Survey

S. Viaene, M. Baes, G. Bendo +11

The dust in nearby galaxies absorbs a fraction of the UV-optical-near-infrared radiation produced by stars. This energy is consequently re-emitted in the infrared. We investigate t…

Star formation in quasar hosts and the origin of radio emission in radio-quiet quasars

Nadia L. Zakamska, Kelly Lampayan, Andreea Petric +11

Radio emission from radio-quiet quasars may be due to star formation in the quasar host galaxy, to a jet launched by the supermassive black hole, or to relativistic particles accel…

The Infrared Database of Extragalactic Observables from Spitzer I: the redshift catalog

Antonio Hernán-Caballero, Henrik W. W. Spoon, Vianney Lebouteiller +2

This is the first of a series of papers on the Infrared Database of Extragalactic Observables from Spitzer (IDEOS). In this work we describe the identification of optical counterpa…

Evidence for a change in the dominant satellite galaxy quenching mechanism at z=1

Michael L. Balogh, Sean L. McGee, Angus Mok +14

We present an analysis of galaxies in groups and clusters at , from the GCLASS and GEEC2 spectroscopic surveys. We compute a "conversion fraction" that…

The HerMES sub-millimetre local and low-redshift luminosity functions

L. Marchetti, M. Vaccari, A. Franceschini +44

We used wide area surveys over 39 deg by the HerMES collaboration, performed with the Herschel Observatory SPIRE multi-wavelength camera, to estimate the low-redshift, $0.02<z<…

A Formation Scenario for the Disk of Satellites: Accretion of Satellites during Mergers

Rory Smith, Pierre-Alain Duc, Frederic Bournaud +1

The Disk of Satellites (DoS) observed in the Andromeda galaxy is a thin and extended group of satellites, nearly perpendicular to the disk plane, that share a common direction of r…
