Small and Complex II: Characterizing the Disk and Stellar Envelope of Edge-on Massive Compact Galaxies
A. Schnorr-Müller, K. Slodkowski Clerici, F. Pinna +7
We present multi-component photometric decompositions of -band Hyper Suprime-Cam images for a sample of 75 edge-on massive compact galaxies (MCGs) at , selected as $+2σ…
Small and Complex I: The Three Component Structure of Massive Compact Quiescent Galaxies
K. Slodkowski Clerici, A. Schnorr-Müller, A. C. Santiago-Menezes +6
We investigate the morphology and structural properties of 246 massive compact quiescent galaxies (MCGs; -, -km\,s$^{-1}…
Low-mass stars dominate the hot (0.7 keV) Galactic X-ray emission
G. Ponti, M. C. H. Yeung, G. Stel +12
The circumgalactic medium (CGM) of the Milky Way is composed of a tenuous atmosphere filled with multi-phase plasma, including a warm-hot virialised component. Recent studies sugge…
Broadband maps of eROSITA and their comparison with the ROSAT survey
Xueying Zheng, Gabriele Ponti, Michael Freyberg +13
By June of 2020, the extended ROentgen Survey with an Imaging Telescope Array (eROSITA) on board the Spectrum Roentgen Gamma observatory had completed its first of the planned eigh…
The warm-hot circumgalactic medium of the Milky Way as seen by eROSITA
N. Locatelli, G. Ponti, X. Zheng +7
The first all-sky maps of the diffuse emission of high ionization lines observed in X-rays by SRG/eROSITA, provide an excellent probe for the study of the warm-hot phase (T~10^6 K)…
