Mean Occupation Function of High-redshift Quasars from the Planck Cluster Catalog
Myers, Adam D.; Chakraborty, Priyanka; Chatterjee, Suchetana +1 more
We characterize the distribution of quasars within dark matter halos using a direct measurement technique for the first time at redshifts as high as z ∼ 1. Using the Planck Sunyaev-Zeldovich (SZ) catalog for galaxy groups and the Sloan Digital Sky Survey (SDSS) DR12 quasar data set, we assign host clusters/groups to the quasars and make a measurem…
DustPedia: A Definitive Study of Cosmic Dust in the Local Universe
Bianchi, S.; Smith, M.; Fritz, J. +20 more
The European Space Agency has invested heavily in two cornerstones missions: Herschel and Planck. The legacy data from these missions provides an unprecedented opportunity to study cosmic dust in galaxies so that we can, for example, answer fundamental questions about the origin of the chemical elements, physical processes in the interstellar medi…
An Overview of the Dwarf Galaxy Survey
Poglitsch, A.; Sturm, E.; Ciesla, L. +38 more
The Dwarf Galaxy Survey (DGS) program is studying low-metallicity galaxies using 230 hr of far-infrared (FIR) and submillimetre (submm) photometric and spectroscopic observations of the Herschel Space Observatory and draws from this a rich database of a wide range of wavelengths tracing the dust, gas and stars. This sample of 50 galaxies includes …
The Star Formation Reference Survey. I. Survey Description and Basic Data
Sturm, E.; Barmby, P.; Zezas, A. +17 more
Star formation is arguably the most important physical process in the cosmos. It is a fundamental driver of galaxy evolution and the ultimate source of most of the energy emitted by galaxies in the local universe. A correct interpretation of star formation rate (SFR) measures is therefore essential to our understanding of galaxy formation and evol…
