A New Fast Silicon Photomultiplier Photometer

open access: yesActa Polytechnica, 2011
The Crab pulsar is one of the most intensively studied X-ray/optical objects, but up to now only a small number of research groups have based their photometers on SiPM technology.

COBIPULSE: A Systematic Search for Compact Binary Millisecond Pulsars

open access: yesThe Astrophysical Journal
We report here the results obtained from a systematic optical photometric survey aimed at finding new compact binary millisecond pulsars (also known as “spiders”): the COmpact BInary PULsar SEarch. We acquired multiband optical images over 1 yr around 33

Free–Free Gaunt Factors for Atmospheres of Accreting Pulsars Observable with X-Ray Space Missions

open access: yesThe Astrophysical Journal
Free–free Gaunt factors for X-ray absorption by hot plasma in the presence of a strong magnetic field are reported. Modified formulae are used for application to the nonlocal thermodynamic equilibrium conditions found in accreting pulsar atmospheres ...
