Galactic Science with Ultra-High Angular Resolution X-ray Imaging
Paul A. Draghis, Jeremy Hare, Mayura Balakrishnan +8
Milli- to micro-arcsecond X-ray imaging will open a new observational regime for Galactic astrophysics by resolving physical scales that are inaccessible to current X-ray observato…
Front-row seat of the recent R Aqr periastron passage: X-ray multi-epoch spectral and spatial analysis
A. Sacchi, M. Karovska, J. Raymond +7
We report on the X-ray spectral and spatial evolution of the Symbiotic star R Aqr. Through a multi-epoch observational campaign performed with Chandra between 2017 and 2022, we stu…
Long-term X-ray Variability of the Symbiotic System RT Cru based on Chandra Spectroscopy
A. Danehkar, M. Karovska, J. J. Drake +1
RT Cru belongs to the rare class of hard X-ray emitting symbiotics, whose origin is not yet fully understood. In this work, we have conducted a detailed spectroscopic analysis of X…
Revisiting the complex nuclear region of NGC 6240 with Chandra
G. Fabbiano, A. Paggi, M. Karovska +3
We present a reanalysis of the cumulative ACIS S Chandra data set pointed at the double AGNs of the NGC 6240 merging galaxy, focusing on the hard energy bands containing the hard s…
High-Energy Photon and Particle Effects onExoplanet Atmospheres and Habitability
Jeremy J. Drake, Julián D. Alvarado-Gómez, Vladimir Airapetian +41
It is now recognized that energetic stellar photon and particle radiation evaporates and erodes planetary atmospheres and controls upper atmospheric chemistry. Key exoplanet host s…
Opportunities for Multimessenger Astronomy in the 2020s
E. Burns, A. Tohuvavohu, J. M. Bellovary +22
Electromagnetic observations of the sky have been the basis for our study of the Universe for millennia, cosmic ray studies are now entering their second century, the first neutrin…
