Abundance and temperature distributions in the hot intra-cluster gas of Abell 4059
François Mernier, Jelle de Plaa, Lorenzo Lovisari +5
Using the EPIC and RGS data from a deep (~200 ks) XMM-Newton observation, we investigate the temperature structure (kT and sigma_T ) and the abundances of 9 elements (O, Ne, Mg, Si…
Coordinated X-ray, Ultraviolet, Optical, and Radio Observations of the PSR J1023+0038 System in a Low-mass X-ray Binary State
Slavko Bogdanov, Anne M. Archibald, Cees Bassa +14
The PSR J1023+0038 binary system hosts a neutron star and a low-mass, main-sequence-like star. It switches on year timescales between states as an eclipsing radio millisecond pulsa…
Accretion-powered pulsations in an apparently quiescent neutron star binary
Anne M. Archibald, Slavko Bogdanov, Alessandro Patruno +10
Accreting millisecond X-ray pulsars are an important subset of low-mass X-ray binaries in which coherent X-ray pulsations can be observed during occasional, bright outbursts (X-ray…
Oxygen emission in remnants of thermonuclear supernovae as a probe for their progenitor system
D. Kosenko, W. Hillebrandt, M. Kromer +3
Recent progress in numerical simulations of thermonuclear supernova explosions brings up a unique opportunity in studying the progenitors of Type Ia supernovae. Coupling state-of-t…
The Radiative Efficiency of a Radiatively Inefficient Accretion Flow
C. R. D'Angelo, J. K. Fridriksson, C. Messenger +1
A recent joint XMM-Newton/Nuclear Spectroscopic Telescope Array (NuSTAR) observation of the accreting neutron star Cen X-4 () revealed a hard…
The growth of the galaxy cluster Abell 85: mergers, shocks, stripping and seeding of clumping
Y. Ichinohe, N. Werner, A. Simionescu +5
We present the results of deep Chandra, XMM-Newton and Suzaku observations of the nearby galaxy cluster Abell 85, which is currently undergoing at least two mergers, and in additio…
Multiwavelength campaign on Mrk 509 XIV. Chandra HETGS spectra
J. S. Kaastra, J. Ebrero, N. Arav +14
We present in this paper the results of a 270 ks Chandra HETGS observation in the context of a large multiwavelength campaign on the Seyfert galaxy Mrk 509. The HETGS spectrum allo…
The Vela Pulsar With an Active Fallback Disk
Gökçe Özsükan, K. Yavuz Ekşi, Valeri Hambaryan +4
Fallback disks are expected to form around young neutron stars. The presence of these disks can be revealed by their blackbody spectrum in the infrared, optical and UV bands. We pr…
Constraining the neutrino emission of gravitationally lensed Flat-Spectrum Radio Quasars with ANTARES data
S. Adrián-Martínez, A. Albert, M. André +134
This paper proposes to exploit gravitational lensing effects to improve the sensitivity of neutrino telescopes to the intrinsic neutrino emission of distant blazar populations. Thi…
NuSTAR Observations of the State Transition of Millisecond Pulsar Binary PSR J1023+0038
Shriharsh P. Tendulkar, Chengwei Yang, Hongjun An +19
We report NuSTAR observations of the millisecond pulsar - low mass X-ray binary (LMXB) transition system PSR J1023+0038 from June and October 2013, before and after the formation o…
A fast and long-lived outflow from the supermassive black hole in NGC 5548
J. S. Kaastra, G. A. Kriss, M. Cappi +31
Supermassive black holes in the nuclei of active galaxies expel large amounts of matter through powerful winds of ionized gas. The archetypal active galaxy NGC 5548 has been studie…
Characterizing the V-band light-curves of hydrogen-rich type II supernovae
Joseph P. Anderson, Santiago González-Gaitán, Mario Hamuy +26
We present an analysis of the diversity of V-band light-curves of hydrogen-rich type II supernovae. Analyzing a sample of 116 supernovae, several magnitude measurements are defined…
A Search for Time Dependent Neutrino Emission from Microquasars with the ANTARES Telescope
S. Adrián-Martínez, A. Albert, M. André +143
Results are presented on a search for neutrino emission from a sample of six microquasars, based on the data collected by the ANTARES neutrino telescope between 2007 and 2010. By m…
A state change in the low-mass X-ray binary XSS J12270-4859
C. G. Bassa, A. Patruno, J. W. T. Hessels +10
Millisecond radio pulsars acquire their rapid rotation rates through mass and angular momentum transfer in a low-mass X-ray binary system. Recent studies of PSR J1824-2452I and PSR…
X-ray Observations of XSS J12270-4859 in a New Low State: A Transformation to a Disk-Free Rotation-Powered Pulsar Binary
Slavko Bogdanov, Alessandro Patruno, Anne M. Archibald +4
We present XMM-Newton and Chandra observations of the low-mass X-ray binary XSS J12270--4859, which experienced a dramatic decline in optical/X-ray brightness at the end of 2012, i…

S. Adrián-Martínez, A. Albert, M. André +133
This paper reports a search for spatial clustering of the arrival directions of high energy muon neutrinos detected by the ANTARES neutrino telescope. An improved two-point correla…
Detecting gravitational waves from the galactic center with Pulsar Timing
Alak Ray, Bence Kocsis, Simon Portegies Zwart
Black holes orbiting the Super Massive Black Hole (SMBH) Sgr A* in the Milky-way galaxy center (GC) generate gravitational waves. The spectrum, due to stars and black holes, is con…
