First measurement of the muon antineutrino double-differential charged-current quasielastic cross section
(American Physical Society, 2013-08-02)
The largest sample ever recorded of (nu) over bar (mu) charged-current quasielastic (CCQE, (nu) over bar (mu) + p -> mu(+) + n) candidate events is used to produce the minimally model-dependent, flux-integrated double-differential ...
Herschel PEP/HerMES: the redshift evolution (0 <= z <= 4) of dust attenuation and of the total (UV plus IR) star formation rate density
(EDP Sciences, 2013-06)
Using new homogeneous luminosity functions (LFs) in the far-ultraviolet (FUV) from VVDS and in the far-infrared (FIR) from Herschel/PEP and Herschel/HerMES, we studied the evolution of the dust attenuation with redshift. ...
Multiwavelength campaign on Mrk 509 VIII. Location of the X-ray absorber
(EDP Sciences, 2012-03)
Aims. More than half of all active galactic nuclei show strong photoionised outflows. A major uncertainty in models for these outflows is the distance of the gas to the central black hole. We use the results of a massive ...
Multiwavelength campaign on Mrk 509 XI. Reverberation of the Fe K alpha line
(EDP Sciences, 2013-01)
Context. We report on a detailed study of the Fe K emission/absorption complex in the nearby, bright Seyfert 1 galaxy Mrk 509. The study is part of an extensive XMM-Newton monitoring consisting of 10 pointings (~60 ks each) ...
Multiwavelength campaign on Mrk 509 III. The 600 ks RGS spectrum: unravelling the inner region of an AGN
(EDP Sciences, 2011-10)
We present the results of our 600 ks RGS observation as part of the multiwavelength campaign on Mrk 509. The very high quality of the spectrum allows us to investigate the ionized outflow with an unprecedented accuracy due ...
Multiwavelength campaign on Mrk 509 X. Lower limit on the distance of the absorber from HST COS and STIS spectroscopy
(EDP Sciences, 2012-08)
Aims. Active galactic nuclei (AGN) often show evidence of photoionized outflows. A major uncertainty in models for these outflows is the distance (R) to the gas from the central black hole. In this paper we use the HST/COS ...
Simultaneous XMM-Newton and HST-COS observation of 1H0419-577 The absorbing and emitting ionized gas
(EDP Sciences, 2013-08)
In this paper we analyze the X-ray, UV, and optical data of the Seyfert 1.5 galaxy 1H0419-577 with the aim of detecting and studying an ionized-gas outflow. The source was observed simultaneously in the X-rays with XMM-Newton ...
Comparison of the calorimetric and kinematic methods of neutrino energy reconstruction in disappearance experiments
(Amer Physical Soc, 2015-10-22)
Multiwavelength campaign on Mrk 509 I. Variability and spectral energy distribution
(EDP Sciences, 2011-10)
Context. Active galactic nuclei (AGN) show a wealth of interesting physical processes, some of which are poorly understood. In a broader context, they play an important role in processes that are far beyond their immediate ...
XMM-Newton RGS observation of the warm absorber in Mrk 279
(EDP Sciences, 2010-09-10)
Context. The Seyfert 1 galaxy Mrk 279 was observed by XMM-Newton in November 2005 on three consecutive orbits, showing significant short-scale variability (average soft band variation in flux ~20%). The source is known to ...
