Lynx X-Ray Observatory: an overview [PDF]

Journal of Astronomical Telescopes, Instruments, and Systems, 2019
Lynx, one of the four strategic mission concepts under study for the 2020 Astrophysics Decadal Survey, provides leaps in capability over previous and planned x-ray missions and provides synergistic observations in the 2030s to a multitude of space- and ground-based observatories across all wavelengths.

Ultraluminous X-ray bursts in two ultracompact companions to nearby elliptical galaxies [PDF]

Nature, 2016
A flaring X-ray source was found near the galaxy NGC 4697 (ref. 1). Two brief flares were seen, separated by four years. During each flare, the flux increased by a factor of 90 on a timescale of about one minute.

Mapping the intracluster medium temperature in the era of NIKA2 and MUSTANG-2 [PDF]

EPJ Web of Conferences, 2022
We present preliminary results from an on-going program that aims at mapping the intracluster medium (ICM) temperature of high redshift galaxy clusters from the MaDCoWS sample using a joint analysis of shallow X-ray data obtained by Chandra and high ...

X-Ray Emissions from Accreting White Dwarfs: A Review [PDF]

, 2017
Interacting binaries in which a white dwarf accretes material from a companion—cataclysmic variables (CVs) in which the mass donor is a Roche-lobe filling star on or near the main sequence, and symbiotic stars in which the mass donor is a late type giant—

Cyclone Hard X-Ray Observatory [PDF]

SPIE Proceedings, 2000
In response to the recent NASA-SMEX Announcement of Opportunity, our collaboration proposed Cyclone, the Cyclotron/Nuclear Explorer. Cyclone is a broadband pointed astrophysical observatory, combining the highest spectral resolutions (E/(Delta) E approximately 30 - 300) and angular resolutions (15') achieved in the optimized hard X-ray range (10 - 200 ...

The International X-ray Observatory [PDF]

AIP Conference Proceedings, 2010
The International X-ray Observatory (IXO) is a joint ESA-JAXA-NASA effort to address fundamental and timely questions in astrophysics: What happens close to a black hole? How did supermassive black holes grow? How does large scale structure form? What is the connection between these processes? To address these questions IXO will employ optics with 3 sq

MAGNETAR-LIKE X-RAY BURSTS FROM A ROTATION-POWERED PULSAR, PSR J1119–6127 [PDF]

, 2016
Two energetic hard X-ray bursts from the rotation-powered pulsar PSR J1119−6127 recently triggered the Fermi and Swift space observatories. We have performed in-depth spectral and temporal analyses of these two events.
