The Pulsar in the Crab Nebula
Natalia Lewandowska
The Crab pulsar belongs to one of the most studied stellar objects in the sky. Since its accidental detection in 1968, its pulsed emission has been observed throughout most of the…
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…
MAGIC detection of short-term variability of the high-peaked BL Lac object 1ES 0806+524
MAGIC Collaboration, J. Aleksić, S. Ansoldi +152
The high-frequency-peaked BL Lac (HBL) 1ES 0806+524 (z = 0.138) was discovered in VHE rays in 2008. Until now, the broad-band spectrum of 1ES 0806+524 has been only poorly char…
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…
