Gas expulsion in massive star clusters? Constraints from observations of young and gas-free objects
Martin G. H. Krause, Corinne Charbonnel, Nate Bastian +1
Gas expulsion is a central concept in some of the models for multiple populations and the light-element anticorrelations in globular clusters. If the star formation efficiency was…
Gamma-ray spectroscopy of Positron Annihilation in the Milky Way
Thomas Siegert, Roland Diehl, Gerasim Khachatryan +5
The annihilation of positrons in the Galaxy's interstellar medium produces characteristic gamma-rays with a line at 511 keV. This emission has been observed with the spectrometer S…
Stellar feedback efficiencies: supernovae versus stellar winds
Katharina M. Fierlinger, Andreas Burkert, Evangelia Ntormousi +5
Stellar winds and supernova (SN) explosions of massive stars ("stellar feedback") create bubbles in the interstellar medium (ISM) and insert newly produced heavy elements and kinet…
Squeezed between shells? On the origin of the Lupus I molecular cloud. APEX/LABOCA, Herschel, and Planck observations
Benjamin Gaczkowski, Thomas Preibisch, Thomas Stanke +7
The Lupus I cloud is found between the Upper-Scorpius (USco) and the Upper-Centaurus-Lupus (UCL) sub-groups of the Sco-Cen OB-association, where the expanding USco H I shell appear…
Revisiting INTEGRAL/SPI observations of 44Ti from Cassiopeia A
Thomas Siegert, Roland Diehl, Martin G. H. Krause +1
The 340-year old supernova remnant Cassiopeia A at 3.4 kpc distance is the best-studied young core-collapse supernova remnant. Nucleosynthesis yields in radioactive isotopes have b…
The formation of regular interarm magnetic fields in spiral galaxies
David Moss, Rodion Stepanov, Marita Krause +2
Observations of regular magnetic fields in several nearby galaxies reveal magnetic arms situated between the material arms. The nature of these magnetic arms is a topic of active d…
