The SRG/eROSITA diffuse soft X-ray background II. spectra and morphology of the eROSITA bubbles in the western Galactic hemisphere

Michael C. H. Yeung, Martin G. F. Mayer, Andy Strong +15

The eROSITA bubbles (eRObub) were discovered in 2020 in the first SRG/eROSITA All-Sky Survey, and are among the most extended structures in the X-ray sky. Using eROSITA all-sky map…

SRG/eROSITA X-ray shadowing study of giant molecular clouds

Michael C. H. Yeung, Michael J. Freyberg, Gabriele Ponti +3

SRG/eROSITA is situated in a halo orbit around L2 where the highly variable solar wind charge exchange (SWCX) emission from Earth's magnetosheath is expected to be negligible. The…

Positron Annihilation in the Galaxy

Carolyn A. Kierans, John F. Beacom, Steve Boggs +27

The 511 keV line from positron annihilation in the Galaxy was the first -ray line detected to originate from outside our solar system. Going into the fifth decade since the dis…

The SRG/eROSITA diffuse soft X-ray background. I. The local hot bubble in the western Galactic hemisphere

Michael C. H. Yeung, Gabriele Ponti, Michael J. Freyberg +10

The SRG/eROSITA All-Sky Surveys (eRASSs) combine the advantages of complete sky coverage and the energy resolution provided by the charge couple device and offer the most holistic…

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…

All-sky Medium Energy Gamma-ray Observatory: Exploring the Extreme Multimessenger Universe

Julie McEnery, Juan Abel Barrio, Ivan Agudo +182

The All-sky Medium Energy Gamma-ray Observatory (AMEGO) is a probe class mission concept that will provide essential contributions to multimessenger astrophysics in the late 2020s…

Soft gamma-ray galactic ridge emission as unveiled by SPI aboard INTEGRAL

Jürgen Knödlseder, Vincent Lonjou, Georg Weidenspointner +6

The origin of the soft gamma-ray (200 keV - 1 MeV) galactic ridge emission is one of the long-standing mysteries in the field of high-energy astrophysics. Population studies at low…
