The pulsar IGR J00291 + 5934 is the fastest-known accretion-powered X-ray pulsar, discovered during a transient outburst in 2004. In this paper, we report on INTEGRAL and Swift observations during the 2015 outburst, which ...

<p>This paper presents an updated scaling relation between the optical luminosity density (LD) of galaxies in the r band and the density of the warm-hot intergalactic medium (WHIM) in cosmic filaments, using the high-resolution ...

<p>The high brightness temperatures, Tb 1013 K, detected in several active galactic nuclei by<br />RadioAstron space VLBI observations challenge theoretical limits. Refractive scattering by<br />the interstellar medium ...

We have analysed 58 high-energy proton events and 36 temporally related near-relativistic electron events from the years 1997 - 2015 for which the velocity dispersion analysis of the first-arriving particles gave the ...

Accretion onto magnetized neutron stars is expected to be centrifugally inhibited at low accretion rates. Several sources including 1A 0535+262, however, are known to pulsate in quiescence at luminosities below the theoretical ...

<p>We investigate the thermal emission and extinction from dust associated with the nearby superluminous supernova (SLSN) 2018bsz. Our dataset has daily cadence and simultaneous optical and near-infrared coverage up to ~ ...

SNR G24.7+0.6 is a 9.5 kyrs radio and gamma-ray supernova remnant evolving in a dense medium. In the GeV regime, SNR G24.7+0.6 (3FHL J1834.1-0706e/FGFS J1834.1-0706) shows a hard spectral index (Gamma similar to 2) up to ...

<div><p>The availability of updated model atmospheres for red supergiants and improvements in single and binary stellar evolution models, together with previously unpublished data, prompted us to revisit the progenitor of ...
