Supernovae without host galaxies? The low surface brightness host of SN 2009Z
P. -C. Zinn, M. Stritzinger, J. Braithwaite +5
A remarkable fraction of supernovae (SNe) have no obvious host galaxy. Two possible explanations are that (i) the host galaxy is simply not detected within the sensitivity of the a…
Supernovae without host galaxy? - Hypervelocity stars in foreign galaxies
Peter-Christian Zinn, Philipp Grunden, Dominik J. Bomans
Harvesting the SAI supernova catalog, we search for SNe that apparently do not occur within a distinct host galaxy but lie a great distance apart from their assigned host galaxy. A…
Detecting Quasars in Large-Scale Astronomical Surveys
Fabian Gieseke, Kai Lars Polsterer, Andreas Thom +5
We present a classification-based approach to identify quasi-stellar radio sources (quasars) in the Sloan Digital Sky Survey and evaluate its performance on a manually labeled trai…
Infrared-Faint Radio Sources: A Cosmological View - AGN Number Counts, the Cosmic X-Ray Background and SMBH Formation
Peter-Christian Zinn, Enno Middelberg, Edo Ibar
Context. Infrared Faint Radio Sources (IFRS) are extragalactic emitters clearly detected at radio wavelengths but barely detected or undetected at optical and infrared wavelengths,…
