The atmosphere of Triton was probed directly by observing a ground-based stellar occultation on 6 October 2022. This rare event yielded 23 positive light curves collected from 13 separate observation stations contributing to our campaign. significance this lies in its potential validate the modest pressure fluctuation Triton, phenomenon not definitively verified previous observations, including only five occultations, and Voyager 2 radio 1989. Using an approach consistent with comparable...
Despite their vital importance to understand galaxy evolution and our own Galactic ecosystem, knowledge of the physical properties hot phase Milky Way is still inadequate. However, sensitive SRG/eROSITA large area surveys are now providing us with long sought-after data needed mend this state affairs. We present soft X-ray emission as observed by eROSITA in eFEDS field. measure temperature metal abundance circum-Galactic medium (CGM) be within $kT_{CGM}=0.153-0.178$ keV $Z_{CGM}=0.052-0.072$...
The diffuse Fe XXV (6.7 keV) line emission observed in the Galactic ridge is widely accepted to be produced by a superposition of large number unresolved X-ray point sources. In very central degrees our Galaxy, however, existence an extremely hot ($\sim$7 plasma still under debate. this work we measure using all available XMM-Newton observations centre (GC) and inner disc ($-10^{\circ}$$<\ell<10^{\circ}$, $-2^{\circ}<b></b>
