Spectral Energy Distribution of Markarian 501: Quiescent State vs. Extreme Outburst
The VERITAS Collaboration, V. A. Acciari, T. Arlen +225
The very high energy (VHE; E > 100 GeV) blazar Markarian 501 has a well-studied history of extreme spectral variability and is an excellent laboratory for studying the physical pro…
Dark halo response and the stellar initial mass function in early-type and late-type galaxies
Aaron A. Dutton, Charlie Conroy, Frank C. van den Bosch +6
We investigate the origin of the relations between stellar mass and optical circular velocity for early-type (ETG) and late-type (LTG) galaxies --- the Faber-Jackson (FJ) and Tully…
Insights Into the High-Energy Gamma-ray Emission of Markarian 501 from Extensive Multifrequency Observations in the Fermi Era
LAT collaboration, A. A. Abdo et al., the MAGIC collaboration +6
We report on the gamma-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average LAT gamma-ray spectrum of Mrk 501 can be well descr…
The clustering of massive galaxies at z~0.5 from the first semester of BOSS data
Martin White, M. Blanton, A. Bolton +25
We calculate the real- and redshift-space clustering of massive galaxies at z~0.5 using the first semester of data by the Baryon Oscillation Spectroscopic Survey (BOSS). We study t…
Observations of the Blazar 3C 66A with the MAGIC Telescopes in Stereoscopic Mode
The MAGIC Collaboration, J. Aleksić, L. A. Antonelli +153
We report new observations of the intermediate-frequency peaked BL Lacertae object 3C 66A with the MAGIC telescopes. The data sample we use were taken in 2009 December and 2010 Jan…
Detection of very high energy gamma-ray emission from the Perseus cluster head-tail galaxy IC 310 by the MAGIC telescopes
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +151
We report on the detection with the MAGIC telescopes of very high energy gamma-rays from IC 310, a head-tail radio galaxy in the Perseus galaxy cluster, observed during the interva…
