The dwarf spheroidal satellite galaxies of the Milky Way are some of the most dark-matter-dominated objects known. Due to their proximity, high dark matter content, and lack of ast…
Infrared identification of high-mass X-ray binaries discovered by INTEGRAL
Alexis Coleiro, Sylvain Chaty, Juan A. Zurita Heras +2
Since it started observing the sky, the INTEGRAL satellite has discovered new categories of high mass X-ray binaries (HMXB) in our Galaxy. These observations raise important questi…
The loss-limited electron energy in SN 1006: effects of the shock velocity and of the diffusion process
M. Miceli, F. Bocchino, A. Decourchelle +3
The spectral shape of the synchrotron X-ray emission from SN 1006 reveals the fundamental role played by radiative losses in shaping the high-energy tail of the electron spectrum.…
Measurement of the atmospheric energy spectrum from 100 GeV to 200 TeV with the ANTARES telescope
The ANTARES Collaboration, S. Adrián-Martínez, A. Albert +149
Atmospheric neutrinos are produced during cascades initiated by the interaction of primary cosmic rays with air nuclei. In this paper, a measurement of the atmospheric ν_μ+ \barν_μ…
Towards a dynamical mass of the ultraluminous X-ray source NGC 5408 X-1
D. Cseh, F. Grise, P. Kaaret +5
We obtained multi-epoch Very Large Telescope (VLT) optical spectroscopic data in 2011 and 2012 on the ultraluminous X-ray source (ULX) NGC 5408 X-1. We confirm that the HeII\lambda…
On the nature of the hard X-ray sources SWIFTJ1907.3-2050, IGRJ12123-5802 and IGRJ19552+0044
F. Bernardini, D. de Martino, K. Mukai +7
The INTEGRAL and Swift hard X-ray surveys have identified a large number of new sources, among which many are proposed as Cataclysmic Variables (CVs). Here we present the first det…
A Search for Neutrino Emission from the Fermi Bubbles with the ANTARES Telescope
ANTARES Collaboration, S. Adrián-Martínez, A. Albert +147
Analysis of the Fermi-LAT data has revealed two extended structures above and below the Galactic Centre emitting gamma rays with a hard spectrum, the so-called Fermi bubbles. Hadro…
Modeling the interaction of thermonuclear supernova remnants with circumstellar structures: The case of Tycho's supernova remnant
A. Chiotellis, D. Kosenko, K. M. Schure +2
The well-established Type Ia remnant of Tycho's supernova (SN 1572) reveals discrepant ambient medium density estimates based on either the measured dynamics or on the X-ray emissi…
Limits on Primordial Black Hole evaporation with the H.E.S.S. array of Cherenkov telescopes
J-F. Glicenstein, A. Barnacka, M. Vivier +1
Data collected by the H.E.S.S. array between 2004 and 2012 have been used to search for photon bursts from primordial black hole explosions. Bursts were searched for in a 30 second…
Echoes of multiple outbursts of Sagittarius A* revealed by Chandra
Maïca Clavel, R. Terrier, A. Goldwurm +4
The relatively rapid spatial and temporal variability of the X-ray radiation from some molecular clouds near the Galactic center shows that this emission component is due to the re…
