X-ray emission from magnetized neutron star atmospheres at low mass accretion rates. I. Phase-averaged spectrum
E. Sokolova-Lapa, M. Gornostaev, J. Wilms +12
Recent observations of X-ray pulsars at low luminosities allow, for the first time, to compare theoretical models for the emission from highly magnetized neutron star atmospheres a…
The jet collimation profile at high resolution in BL Lacertae
C. Casadio, N. R. MacDonald, B. Boccardi +14
Controversial studies on the jet collimation profile of BL Lacertae (BL Lac), the eponymous blazar of BL Lac objects class, complicate the scenario in this already puzzling class o…
Observations of the Ultra-compact X-ray Binary 4U 1543-624 in Outburst with NICER, INTEGRAL, Swift, and ATCA
R. M. Ludlam, L. Shishkovsky, P. M. Bult +17
We report on X-ray and radio observations of the ultra-compact X-ray binary 4U 1543-624 taken in August 2017 during an enhanced accretion episode. We obtained NICER monitoring of t…
First Results on the Search for Chameleons with the KWISP Detector at CAST
S. Arguedas Cuendis, J. Baier, K. Barth +50
We report on a first measurement with a sensitive opto-mechanical force sensor designed for the direct detection of coupling of real chameleons to matter. These dark energy candida…
Breaking the limit: Super-Eddington accretion onto black holes and neutron stars
M. Brightman, M. Bachetti, H. P. Earnshaw +10
With the recent discoveries of massive and highly luminous quasars at high redshifts (; e.g. Mortlock et al. 2011), the question of how black holes (BHs) grow in the early…
K-shell photoionization of Na-like to Cl-like ions of Mg, Si, S, Ar, and Ca
M. C. Witthoeft, J. García, T. R. Kallman +4
We present -matrix calculations of photoabsorption and photoionization cross sections across the K-edge of Mg, Si, S, Ar, and Ca ions with more than 10 electrons. The calculatio…
