The eROSITA telescope array aboard the Spektrum Roentgen Gamma (SRG) satellite began surveying sky in December 2019, with aim of producing all-sky X-ray source lists and maps an unprecedented depth. Here we present catalogues both point-like extended sources using data acquired first six months survey operations (eRASS1; completed June 2020) over half whose proprietary rights lie German Consortium. We describe observation process, analysis pipelines, characteristics sources. With nearly 930...
Recent spectroscopic observations of the fine-structure line ionized carbon (C^+), using Stratospheric Observatory for Infrared Astronomy (SOFIA), have revealed expanding shells in Galactic regions. We report discovery a bubble-shaped source (S144 RCW79 GLIMPSE survey), associated with compact region, excited by single O7.5--9.5V/III star, which is consistent scenario that bubble still mostly ``filled'' C^+. This indicates most likely very early evolutionary state, stellar wind has not yet...
