Orbital and superorbital variability of LS I +61 303 at low radio frequencies with GMRT and LOFAR
B. Marcote, M. Ribó, J. M. Paredes +23
LS I +61 303 is a gamma-ray binary that exhibits an outburst at GHz frequencies each orbital cycle of 26.5 d and a superorbital modulation with a period of 4.6…
Multiwavelength Study of Quiescent States of Mrk 421 with Unprecedented Hard X-Ray Coverage Provided by NuSTAR in 2013
M. Baloković, D. Paneque, G. Madejski +305
We present coordinated multiwavelength observations of the bright, nearby BL Lac object Mrk 421 taken in 2013 January-March, involving GASP-WEBT, Swift, NuSTAR, Fermi-LAT, MAGIC, V…
The 2-10 keV unabsorbed luminosity function of AGN from the XMM-Newton LSS, CDFS and COSMOS surveys
P. Ranalli, E. Koulouridis, I. Georgantopoulos +15
The XMM-LSS, XMM-COSMOS, and XMM-CDFS surveys are complementary in terms of sky coverage and depth. Together, they form a clean sample with the least possible variance in instrumen…
NuSTAR catches the unveiling nucleus of NGC 1068
A. Marinucci, S. Bianchi, G. Matt +15
We present a NuSTAR and XMM-Newton monitoring campaign in 2014/2015 of the Compton-thick Seyfert 2 galaxy, NGC 1068. During the August 2014 observation, we detect with NuSTAR a flu…
The origin of the X-ray-emitting object moving away from PSR B1259-63
Maxim V. Barkov, Valenti Bosch-Ramon
A mysterious X-ray-emitting object has been detected moving away from the high-mass gamma-ray binary PSR B1259-63, which contains a non-accreting pulsar and a Be star whose winds c…
Teraelectronvolt pulsed emission from the Crab pulsar detected by MAGIC
MAGIC Collaboration, S. Ansoldi, L. A. Antonelli +139
Aims: To investigate the extension of the very-high-energy spectral tail of the Crab pulsar at energies above 400 GeV. Methods: We analyzed 320 hours of good quality data of…
First NuSTAR Observations of Mrk 501 within a Radio to TeV Multi-Instrument Campaign
A. Furniss, K. Noda, S. Boggs +273
We report on simultaneous broadband observations of the TeV-emitting blazar Markarian 501 between 1 April and 10 August 2013, including the first detailed characterization of the s…
Very-high-energy γ-ray observations of novae and dwarf novae with the MAGIC telescopes
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +148
Context. In the last five years the Fermi Large Area Telescope (LAT) instrument detected GeV γ-ray emission from five novae. The GeV emission can be interpreted in terms of an inve…
Physical properties of the gamma-ray binary LS 5039 through low and high frequency radio observations
B. Marcote, M. Ribó, J. M. Paredes +1
We have studied in detail the 0.15-15 GHz radio spectrum of the gamma-ray binary LS 5039 to look for a possible turnover and absorption mechanisms at low frequencies, and to constr…
On the formation and evolution of the first Be star in a black hole binary MWC 656
M. Grudzinska, K. Belczynski, J. Casares +8
We find that the formation of MWC 656 (the first Be binary containing a black hole) involves a common envelope phase and a supernova explosion. This result supports the idea that a…
Sub-mm Jet Properties of the X-Ray Binary Swift J174526
A. J. Tetarenko, G. R. Sivakoff, J. C. A. Miller-Jones +12
We present the results of our observations of the early stages of the 2012--2013 outburst of the transient black hole X-ray binary (BHXRB), Swift J174526, with the VLA, SMA, and…
Radio monitoring of the hard state jets in the 2011 outburst of MAXI J1836-194
T. D. Russell, J. C. A. Miller-Jones, P. A. Curran +25
MAXI J1836-194 is a Galactic black hole candidate X-ray binary that was discovered in 2011 when it went into outburst. In this paper, we present the full radio monitoring of this s…
Evidence of coupling between the thermal and nonthermal emission in the gamma-ray binary LS I +61 303
X. Paredes-Fortuny, M. Ribó, V. Bosch-Ramon +3
The gamma-ray binary LS I +61 303 is composed of a Be star and a compact companion orbiting in an eccentric orbit. Variable flux modulated with the orbital period of ~26.5 d has be…
The 2009 multiwavelength campaign on Mrk 421: Variability and correlation studies
MAGIC Collaboration, J. Aleksić, S. Ansoldi +270
We performed a 4.5-month multi-instrument campaign (from radio to VHE gamma rays) on Mrk421 between January 2009 and June 2009, which included VLBA, F-GAMMA, GASP-WEBT, Swift, RXTE…
MAGIC observations of MWC 656, the only known Be/BH system
J. Aleksić, S. Ansoldi, L. A. Antonelli +149
Context: MWC 656 has recently been established as the first observationally detected high-mass X-ray binary system containing a Be star and a black hole (BH). The system has been a…
Non-thermal emission from standing relativistic shocks: an application to red giant winds interacting with AGN jets
V. Bosch-Ramon
Galactic and extragalactic relativistic jets have rich environments that are full of moving objects, such as stars and dense clumps. These objects can enter into the jets and gener…
The origin of the cosmic gamma-ray background in the MeV range
Pilar Ruiz-Lapuente, Lih-Sin The, Dieter Hartmann +5
There has been much debate about the origin of the diffuse --ray background in the MeV range. At lower energies, AGNs and Seyfert galaxies can explain the background, but not ab…
