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…
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…
Shockingly Bright Warm Carbon Monoxide Molecular Features in the Supernova Remnant Cassiopeia A Revealed by JWST
J. Rho, S. -H. Park, R. Arendt +36
We present JWST NIRCam (F356W and F444W filters) and MIRI (F770W) images and NIRSpec- IFU spectroscopy of the young supernova remnant Cassiopeia A (Cas A). We obtained the data as…
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…
A JWST Survey of the Supernova Remnant Cassiopeia A
Dan Milisavljevic, Tea Temim, Ilse De Looze +43
We present initial results from a JWST survey of the youngest Galactic core-collapse supernova remnant Cassiopeia A (Cas A), made up of NIRCam and MIRI imaging mosaics that map emi…
