Cosmic evolution and metal aversion in super-luminous supernova host galaxies
S. Schulze, T. Krühler, G. Leloudas +21
The SUperluminous Supernova Host galaxIES (SUSHIES) survey aims to provide strong new constraints on the progenitors of superluminous supernovae (SLSNe) by understanding the relati…
Galaxy gas as obscurer: II. Separating the galaxy-scale and nuclear obscurers of Active Galactic Nuclei
Johannes Buchner, Franz E. Bauer
The "torus" obscurer of Active Galactic Nuclei (AGN) is poorly understood in terms of its density, substructure and physical mechanisms. Large X-ray surveys provide model boundary…
Galaxy gas as obscurer: I. GRBs x-ray galaxies and find a N_H ~ M* relation
Johannes Buchner, Steve Schulze, Franz E. Bauer
An important constraint for galaxy evolution models is how much gas resides in galaxies, in particular at the peak of star formation z=1-3. We attempt a novel approach by letting l…
The Sloan Digital Sky Survey Quasar Catalog: twelfth data release
Isabelle Pâris, Patrick Petitjean, Nicholas P. Ross +43
We present the Data Release 12 Quasar catalog (DR12Q) from the Baryon Oscillation Spectroscopic Survey (BOSS) of the SDSS-III. This catalog includes all SDSS-III/BOSS objects that…
Global Dynamics, Blow-Up, and Bianchi Cosmology
Nitsan Ben-Gal, Bernhard Brehm, Johannes Buchner +8
Many central problems in geometry, topology, and mathematical physics lead to questions concerning the long-time dynamics of solutions to ordinary and partial differential equation…
X-ray spectral properties of the AGN sample in the northern XMM-XXL field
Zhu Liu, Andrea Merloni, Antonis Georgakakis +7
In this paper we describe and publicly release a catalogue consisting of 8445 point-like X-ray sources detected in the XMM-XXL north survey. For the 2512 AGN which have reliable sp…
