Multiband variability studies and novel broadband SED modeling of Mrk 501 in 2009
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +290
We present an extensive study of the BL Lac object Mrk 501 based on a data set collected during the multi-instrument campaign spanning from 2009 March 15 to 2009 August 1 which inc…
A search for spectral hysteresis and energy-dependent time lags from X-ray and TeV gamma-ray observations of Mrk 421
A. U. Abeysekara, S. Archambault, A. Archer +220
Blazars are variable emitters across all wavelengths over a wide range of timescales, from months down to minutes. It is therefore essential to observe blazars simultaneously at di…
Very High-Energy Gamma-Ray Follow-Up Program Using Neutrino Triggers from IceCube
IceCube Collaboration, M. G. Aartsen, K. Abraham +537
We describe and report the status of a neutrino-triggered program in IceCube that generates real-time alerts for gamma-ray follow-up observations by atmospheric-Cherenkov telescope…
Contributions of the Cherenkov Telescope Array (CTA) to the 6th International Symposium on High-Energy Gamma-Ray Astronomy (Gamma 2016)
The CTA Consortium, :, A. Abchiche +1387
List of contributions from the Cherenkov Telescope Array (CTA) Consortium presented at the 6th International Symposium on High-Energy Gamma-Ray Astronomy (Gamma 2016), July 11-15,…
The RINGO2 and DIPOL Optical Polarisation Catalogue of Blazars
H. Jermak, I. A. Steele, E. Lindfors +9
We present ~2000 polarimetric and ~3000 photometric observations of 15 gamma-ray bright blazars over a period of 936 days (11/10/2008 - 26/10/2012) using data from the Tuorla blaza…
Design and expected performance of a novel hybrid detector for very-high-energy gamma astrophysics
P. Assis, U. Barres de Almeida, A. Blanco +10
Current detectors for Very-High-Energy -ray astrophysics are either pointing instruments with a small field of view (Cherenkov telescopes), or large field-of-view instruments wi…
Long-term multi-wavelength variability and correlation study of Markarian 421 from 2007 to 2009
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +176
We study the multi-band variability and correlations of the TeV blazar Mrk 421 on year time scales, which can bring additional insight on the processes responsible for its broadban…
Super-orbital variability of LS I +61°303 at TeV energies
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +150
The gamma-ray binary LS I +61303 is a well established source from centimeter radio up to very high energy (VHE; E100 GeV). Its broadband emission shows a periodicity…
Multi-Wavelength Observations of the Blazar 1ES 1011+496 in Spring 2008
The MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +158
The BL Lac object 1ES 1011+496 was discovered at Very High Energy gamma-rays by MAGIC in spring 2007. Before that the source was little studied in different wavelengths. Therefore…
Investigating the peculiar emission from the new VHE gamma-ray source H1722+119
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +159
The MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescopes observed the BL Lac object H1722+119 (redshift unknown) for six consecutive nights between 2013 May 17 and 22,…
Deep observation of the NGC 1275 region with MAGIC: search of diffuse gamma-ray emission from cosmic rays in the Perseus cluster
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +154
Clusters of galaxies are expected to be reservoirs of cosmic rays (CRs) that should produce diffuse gamma-ray emission due to their hadronic interactions with the intra-cluster med…
On the rate and on the gravitational wave emission of short and long GRBs
R. Ruffini, J. Rodriguez, M. Muccino +13
On the ground of the large number of gamma-ray bursts (GRBs) detected with cosmological redshift, we classified GRBs in seven subclasses, all with binary progenitors originating gr…
Status of the Cherenkov Telescope Array Project
Ulisses Barres de Almeida
Gamma-ray astronomy holds a great potential for Astrophysics, Particle Physics and Cosmology. The CTA is an inter- national initiative to build the next generation of ground-based…
