Discovery of very high energy gamma-ray emission from the blazar 1ES 0033+595 by the MAGIC telescopes
J. Aleksić, S. Ansoldi, L. A. Antonelli +157
The number of known very high energy (VHE) blazars is , which is very small in comparison to the number of blazars detected in other frequencies. This situation is a hand…
Multiwavelength observations of Mrk 501 in 2008
MAGIC Collaboration, J. Aleksić, S. Ansoldi +256
Mrk 501 is one of the brightest blazars at TeV energies and has been extensively studied since its first VHE detection in 1996. Our goal is to characterize in detail the source gam…
First broadband characterization and redshift determination of the VHE blazar MAGIC J2001+439
MAGIC Collaboration, J. Aleksić, S. Ansoldi +167
We aim to characterize the broadband emission from 2FGL J2001.1+4352, which has been associated with the unknown-redshift blazar MG4 J200112+4352. Based on its gamma-ray spectral p…
The environment of low redshift quasar pairs
Angela Sandrinelli, Renato Falomo, Aldo Treves +2
We investigate the properties of the galaxy environment of a sample of 14 low redshift (z 0.85) quasar physical pairs extracted from SDSS DR10 archives. The pairs have a system…
Discovery of eight z ~ 6 quasars from Pan-STARRS1
E. Bañados, B. P. Venemans, E. Morganson +24
High-redshift quasars are currently the only probes of the growth of supermassive black holes and potential tracers of structure evolution at early cosmic time. Here we present our…
The extent of the MgII absorbing circum-galactic medium of quasars
E. P. Farina, R. Falomo, R. Scarpa +3
We investigate the extent and the properties of the MgII cool, low-density absorbing gas located in the halo and in the circum-galactic environment of quasars, using a sample of 31…
