Pulsed Infrared Emission from Magnetar 4U 0142+61 Detected by JWST

Jeremy Hare, George G. Pavlov, Bettina Posselt +3

We report on a JWST observation of the magnetar 4U 0142+61 on 2024 August 18 with the Near-Infrared Camera (NIRCam). NIRCam observed the magnetar for 33~min in timing mode, providi…

Neutron star heating vs. HST observations

Luis E. Rodríguez, Andreas Reisenegger, Denis González-Caniulef +5

Passively cooling neutron stars (NSs) should reach undetectably low surface temperatures K in less than yr. However, HST observations have revealed likely thermal…

The middle-aged pulsar PSR J1741-2054 and its bow-shock nebula in far ultraviolet

Vadim Abramkin, George G. Pavlov, Yuriy Shibanov +2

Context. The nearby middle-aged gamma-ray pulsar J1741-2054 and its pulsar wind nebula (PWN) have been studied in X-rays, and its bow-shock nebula (BSN) has been investigated in th…

The Variable X-ray Emission of the Cataclysmic Variable V1460 Her with a Rapidly Rotating White Dwarf

Erik B. Monson, George G. Pavlov, Gordon P. Garmire

Using a recent Chandra ACIS observation of the eclipsing cataclysmic variable (CV) V1460 Her (2MASS J16211735+4412541) with a fast-rotating (~s) white dwarf, w…

Probing the spectrum of the magnetar 4U 0142+61 with JWST

Jeremy Hare, George G. Pavlov, Bettina Posselt +3

JWST observed the magnetar 4U 0142+61 with the MIRI and NIRCam instruments within a 77 min time interval on 2022 September 20-21. The low-resolution MIRI spectrum and NIRCam photom…

Multiwavelength pulsations and surface temperature distribution in the middle-aged pulsar B1055-52

Armin Vahdat, Bettina Posselt, George G. Pavlov +3

We present a detailed study of the X-ray emission from PSR B1055-52 using XMM-Newton observations from 2019 and 2000. The phase-integrated X-ray emission from this pulsar is poorly…
