Evidence of stellar oscillations in the post-common envelop binary candidate ASASSN-V J205543.90+240033.5
J. Takata, A. K. H. Kong, X. F. Wang +7
ASASSN-V J205543.90+240033.5 (ASJ2055) is a possible post-common envelope binary system. Its optical photometric data shows an orbital variation about ~days and a fast period…
Dimming of Continuum Captured in Mrk 841: New Clues on the Nature of the Soft X-ray Excess
Missagh Mehdipour, Gerard Kriss, Jelle Kaastra +2
We report on a remarkable change in the spectral energy distribution (SED) of Mrk 841, providing new insights on how the soft X-ray excess emission in active galactic nuclei (AGNs)…
Scientific Objectives of the Hot Universe Baryon Surveyor (HUBS) Mission
Joel Bregman, Renyue Cen, Yang Chen +51
The Hot Universe Baryon Surveyor (HUBS) is a proposed space-based X-ray telescope for detecting X-ray emissions from the hot gas content in our universe. With its unprecedented spa…
XMM-Newton Reflection Grating Spectrometer
Junjie Mao, Frits Paerels, Matteo Guainazzi +1
The past two decades have witnessed the rapid growth of our knowledge of the X-ray Universe thanks to flagship X-ray space observatories like XMM-Newton and Chandra. A significant…
Transient obscuration event captured in NGC 3227 IV. Origin of the obscuring cloud variability
S. Grafton-Waters, J. Mao, M. Mehdipour +13
Obscuration events in type I active galactic nuclei (AGN) have been detected more frequently in recent years. The strong flux decrease in the soft X-ray band between observations h…
The Collisional and Photoionized Plasma in the Polarized NLS1 galaxy Mrk 1239
Margaret Z. Buhariwalla, Luigi C. Gallo, J. Mao +4
Mrk 1239 is a highly polarized NLS1 in the optical band, whose keV spectrum has remained remarkably consistent over more than two decades of observation. Previous analysis…
