- Cosmic BlazEr buttoned upA stylish new study by Remeis astronomers on jetted active galactic nuclei We would like to share a new Astronomy & Astrophysics publication from a team of Remeis astronomers from the X-ray Group of Jörn Wilms presenting the “BlazEr” catalog of blazars and blazar candidates from the first eROSITA all-sky survey (eRASS1). Using eRASS1 data… Read more: Cosmic BlazEr buttoned up
- A Link Between X-ray Spectral Shape and Neutron Star Magnetic FieldsRemeis astronomers have devised a new method for measuring magnetic fields in neutron-star atmospheres. Astronomers from the X-ray Group of Prof. Jörn Wilms at the Dr. Karl Remeis Observatory have uncovered a direct correlation between the shape of X-ray spectra and the magnetic field strength of neutron stars in Be-X-ray binaries. Such systems contain a… Read more: A Link Between X-ray Spectral Shape and Neutron Star Magnetic Fields
- Stellar explosion in our neighborhoodRemeis astronomers have studied the remnant of a very nearby cosmic explosion. Using data from X-ray and radio maps of the entire sky, astronomers from the Remeis Observatory have confirmed and studied the Antlia supernova remnant, a structure formed by a nearby supernova explosion. Due to its closeness and, hence, large extent in the sky… Read more: Stellar explosion in our neighborhood
- X-raying interstellar gas in our cosmic neighborRemeis astronomers have provided the deepest view of diffuse X-ray emission from hot plasma in the Large Magellanic Cloud. When stars explode in violent supernovae, they release an enormous amount of energy, momentum, and material into their surroundings, which leads to lasting imprints on the “ecosystem” of their galaxies. An important signature of this process… Read more: X-raying interstellar gas in our cosmic neighbor
- In loving memory of Dr. Katja PottschmidtDr. Karl Remeis Observatory is deeply saddened by the unexpected passing of our dear friend, colleague, and mentor Dr. Katja Pottschmidt on Tuesday, June 17 2025. Born May 31, 1971, in Aurich, Germany, into a military family (her father was in the German air force), Katja grew up in Aurich and Freising, Germany, in Norfolk,… Read more: In loving memory of Dr. Katja Pottschmidt
