Evaluating the Evidence of Multipolar Surface Magnetic Field in PSR J01081431
Prakash Arumugasamy, Dipanjan Mitra
PSR J01081431 is an old pulsar where the X-ray emission is expected to have a thermal component from the polar cap and a non-thermal component from the magnetosphere. Although t…
Possible phase-dependent absorption feature in the x-ray spectrum of the middle-aged PSR J0659+1414
Prakash Arumugasamy, Oleg Kargaltsev, Bettina Posselt +2
We report on the energy-resolved timing and phase-resolved spectral analysis of X-ray emission from PSR J0659+1414 observed with XMM-Newton and NuSTAR. We find that the new data ru…
X-ray emission from J1446-4701, J1311-3430 and other black widow pulsars
Prakash Arumugasamy, George G. Pavlov, Gordon P. Garmire
We present the results of detailed X-ray analysis of two black-widow pulsars (BWPs), J1446-4701 and J1311-3430. PSR J1446-4701 is a BWP with orbital parameters near the median valu…
XMM-Newton Observations of Young and Energetic Pulsar J2022+3842
P. Arumugasamy, G. G. Pavlov, O. Kargaltsev
We report on EPIC observations of the young pulsar J2022+3842, with a characteristic age of 8.9 kyr. We detected X-ray pulsations and found the pulsation period $P\app…
XMM-Newton observation of the very old pulsar J0108-1431
B. Posselt, P. Arumugasamy, G. G. Pavlov +3
We report on an X-ray observation of the 166 Myr old radio pulsar J0108-1431 with XMM-Newton. The X-ray spectrum can be described by a power-law model with a relatively steep photo…
