Spectro-polarimetric observations of the CIZA J2242.8+5301 northern radio relic: no evidence of high-frequency steepening
Francesca Loi, Matteo Murgia, Valentina Vacca +16
Observations of radio relics at very high frequency (>10 GHz) can help to understand how particles age and are (re-)accelerated in galaxy cluster outskirts and how magnetic fields…
Constraints on the winds of hot subdwarf stars from X-ray observations of two sdB binaries with compact companions: CD -30 11223 and PG 1232-136
S. Mereghetti, N. La Palombara, P. Esposito +5
Little observational data are available on the weak stellar winds of hot subdwarf stars of B spectral type (sdB). Close binary systems composed of an sdB star and a compact object…
A variable absorption feature in the X-ray spectrum of a magnetar
Andrea Tiengo, Paolo Esposito, Sandro Mereghetti +9
Soft gamma-ray repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are slowly rotating, isolated neutron stars that sporadically undergo episodes of long-term flux enhancement (out…
The variable quiescence of Cen X-4
S. Campana, G. L. Israel, L. Stella +2
Cen X-4 is one of the best studied low-mass neutron star transients in quiescence. Thanks to XMM-Newton large throughput, Cen X-4 was observed at the highest signal to noise ever.…
An XMM-Newton study of the 401 Hz accreting pulsar SAX J1808.4-3658 in quiescence
S. Campana, L. Stella, F. Gastaldello +6
SAX J1808.4-3658 is a unique source being the first Low Mass X-ray Binary showing coherent pulsations at a spin period comparable to that of millisecond radio pulsars. Here we pres…
The transient X-ray pulsar 4U 0115+63 from quiescence to outburst through the centrifugal transition
S. Campana, F. Gastaldello, L. Stella +5
We report on a BeppoSAX observation of the transient X-ray pulsar 4U 0115+63 close to periastron. This led to the discovery of a dramatic luminosity variation from ~2x10^34 erg/s t…
