Catching the radio flare in CTA 102: II. VLBI kinematic analysis
C. M. Fromm, E. Ros, M. Perucho +6
We performed multifrequency multiepoch Very Long Baseline Array (VLBA) observations of the blazar CTA 102 during its 2006 radio flare, the strongest ever reported for this source.…
The Simultaneous Low State Spectral Energy Distribution of 1ES 2344+514 from Radio to Very High Energies
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +191
[Abridged] Context. To construct and interpret the spectral energy distribution (SED) of BL Lacertae objects, simultaneous broad-band observations are mandatory. Aims. We present t…
Do magnetars really exist?
Igor Malov
It is shown that there are neither necessary nor sufficient properties to provide unambiguous evidence for including any object in the AXP/SGR class.
The Green Bank Telescope 350 MHz Drift-scan Survey I: Survey Observations and the Discovery of 13 Pulsars
Jason Boyles, Ryan S. Lynch, Scott M. Ransom +17
Over the summer of 2007, we obtained 1191 hours of `drift-scan' pulsar search observations with the Green Bank Telescope at a radio frequency of 350 MHz. Here we describe the surve…
Stochastic particle acceleration and the problem of backgroud plasma overheating
D. O. Chernyshov, V. A. Dogiel, C. M. Ko
The origin of hard X-ray (HXR) excess emission from clusters of galaxies is still an enigma, whose nature is debated. One of the possible mechanism to produce this emission is the…
Results on the primary CR spectrum and composition reconstructed with the SPHERE-2 detector
R. A. Antonov, S. P. Beschapov, E. A. Bonvech +11
First preliminary results of the balloon-borne experiment SPHERE-2 on the all-nuclei primary cosmic rays (PCR) spectrum and primary composition are presented. The primary spectrum…
A Giant Sample of Giant Pulses from the Crab Pulsar
Mitchell B. Mickaliger, Maura A. McLaughlin, Duncan R. Lorimer +6
We observed the Crab pulsar with the 43-m telescope in Green Bank, WV over a timespan of 15 months. In total we obtained 100 hours of data at 1.2 GHz and seven hours at 330 MHz, re…
Radio-to-gamma-ray Monitoring of the Narrow-Line Seyfert 1 Galaxy PMN J0948+0022 from 2008 to 2011
L. Foschini, E. Angelakis, L. Fuhrmann +39
We present more than three years of observations at different frequencies, from radio to high-energy gamma-rays, of the Narrow-Line Seyfert 1 (NLS1) Galaxy PMN J0948+0022 (z=0.585)…
VLBA monitoring of Mrk 421 at 15 GHz and 24 GHz during 2011
R. Lico, M. Giroletti, M. Orienti +13
High-resolution radio observations are ideal for constraining the value of physical parameters in the inner regions of active-galactic-nucleus jets and complement results on multiw…
Multiwavelength Intraday Variability of the BL Lac S5 0716+714
Alok C. Gupta, T. P. Krichbaum, P. J. Wiita +31
We report results from a 1 week multi-wavelength campaign to monitor the BL Lac object S5 0716+714 (on December 9-16, 2009). In the radio bands the source shows rapid (~ (0.5-1.5)…
Chandra X-ray Observations of the Two Brightest Unidentified High Galactic Latitude Fermi-LAT gamma-ray Sources
C. C. Cheung, D. Donato, N. Gehrels +2
We present Chandra ACIS-I X-ray observations of 0FGL J1311.9-3419 and 0FGL J1653.4-0200, the two brightest high Galactic latitude (|b|>10 deg) gamma-ray sources from the 3 month Fe…
Discovery of the Optical/Ultraviolet/Gamma-ray Counterpart to the Eclipsing Millisecond Pulsar J1816+4510
D. L. Kaplan, K. Stovall, S. M. Ransom +21
The energetic, eclipsing millisecond pulsar J1816+4510 was recently discovered in a low-frequency radio survey with the Green Bank Telescope. With an orbital period of 8.7 hr and m…
Variable gamma-ray sky at 1 GeV
M. S. Pshirkov, G. I. Rubtsov
We search for the long-term variability of the γ-ray sky in the energy range E > 1 GeV with 168 weeks of Fermi-LAT data. We perform a full sky blind search for regions with variabl…
