Supergiant fast X-ray transients as an under-luminous class of supergiant X-ray binaries
E. Bozzo, P. Romano, L. Ducci +2
The usage of cumulative luminosity distributions, constructed thanks to the long-term observations available through wide field hard X-ray imagers, has been recently exploited to s…
Large scale distribution of ultra high energy cosmic rays detected at the Pierre Auger Observatory with zenith angles up to 80
The Pierre Auger Collaboration
We present the results of an analysis of the large angular scale distribution of the arrival directions of cosmic rays with energy above 4 EeV detected at the Pierre Auger Observat…
Searches for Anisotropies in the Arrival Directions of the Highest Energy Cosmic Rays Detected by the Pierre Auger Observatory
Pierre Auger Collaboration
We analyze the distribution of arrival directions of ultra-high energy cosmic rays recorded at the Pierre Auger Observatory in 10 years of operation. The data set, about three time…
Search for patterns by combining cosmic-ray energy and arrival directions at the Pierre Auger Observatory
The Pierre Auger Collaboration
Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-ener…
Depth of Maximum of Air-Shower Profiles at the Pierre Auger Observatory: Composition Implications
Pierre Auger Collaboration
Using the data taken at the Pierre Auger Observatory between December 2004 and December 2012, we have examined the implications of the distributions of depths of atmospheric shower…
The orbital period of Swift J1816.7-1613 revealed by the Swift-BAT telescope
V. La Parola, A. Segreto, G. Cusumano +3
We have analyzed the Swift data relevant to the high mass X-ray binary Swift J1816.7-1613. The timing analysis of the BAT survey data unveiled a modulation at a period of P_0=118.5…
Depth of Maximum of Air-Shower Profiles at the Pierre Auger Observatory: Measurements at Energies above 10^17.8 eV
Pierre Auger Collaboration
We report a study of the distributions of the depth of maximum, Xmax, of extensive air-shower profiles with energies above 10^17.8 eV as observed with the fluorescence telescopes o…
Properties of flat-spectrum radio-loud Narrow-Line Seyfert 1 Galaxies
L. Foschini, M. Berton, A. Caccianiga +27
We have conducted a multiwavelength survey of 42 radio loud narrow-1ine Seyfert 1 galaxies (RLNLS1s), selected by searching among all the known sources of this type and omitting th…
A Compton thick AGN in the barred spiral NGC 4785
P. Gandhi, S. Yamada, C. Ricci +5
We present X-ray observations of the active galactic nucleus (AGN) in NGC 4785. The source is a local Seyfert 2 which has not been studied so far in much detail. It was recently de…
Swift Ultraviolet Observations of Supernova 2014J in M82: Large Extinction from Interstellar Dust
Peter J. Brown, Michael T. Smitka, Lifan Wang +8
We present optical and ultraviolet (UV) photometry and spectra of the very nearby and highly reddened supernova (SN) 2014J in M82 obtained with the Swift Ultra-Violet/Optical Teles…
Muons in air showers at the Pierre Auger Observatory: Mean number in highly inclined events
Pierre Auger Collaboration
We present the first hybrid measurement of the average muon number in air showers at ultra-high energies, initiated by cosmic rays with zenith angles between and $80^\ci…
Expected number of supergiant fast X-ray transients in the Milky Way
L. Ducci, V. Doroshenko, P. Romano +2
In the past fifteen years a new generation of X-ray satellites led to the discovery of a subclass of high-mass X-ray binaries (HMXBs) with supergiant companions and a peculiar tran…
NuSTAR Detection Of A Cyclotron Line In The Supergiant Fast X-ray Transient IGR J17544-2619
Varun Bhalerao, Patrizia Romano, John Tomsick +16
We present NuSTAR spectral and timing studies of the Supergiant Fast X-ray Transient (SFXT) IGR J17544-2619. The spectrum is well-described by a ~1 keV blackbody and a hard continu…
Soft X-ray characterisation of the long term properties of Supergiant Fast X-ray Transients
P. Romano, L. Ducci, V. Mangano +3
We perform the first high-sensitivity soft X-ray long-term monitoring with Swift/XRT of three relatively unexplored Supergiant Fast X-ray Transients (SFXTs), IGR J08408-4503, IGR J…
A Targeted Search for Point Sources of EeV Neutrons
The Pierre Auger Collaboration, A. Aab, P. Abreu +482
A flux of neutrons from an astrophysical source in the Galaxy can be detected in the Pierre Auger Observatory as an excess of cosmic-ray air showers arriving from the direction of…
A search for point sources of EeV photons
Pierre Auger Collaboration, A. Aab, P. Abreu +483
Measurements of air showers made using the hybrid technique developed with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for point…
Effective absorbing column density in the gamma-ray burst afterglow X-ray spectra
S. Campana, M. G. Bernardini, V. Braito +9
We investigate the scaling relation between the observed amount of absorption in the X-ray spectra of Gamma Ray Burst (GRB) afterglows and the absorber redshift. Through dedicated…
Probing the radio emission from air showers with polarization measurements
Pierre Auger Collaboration
The emission of radio waves from air showers has been attributed to the so-called geomagnetic emission process. At frequencies around 50 MHz this process leads to coherent radiatio…
