Girls brave cold April weather

April 27, 2017
As in previous years at the end of April, MPA invited 30 girls to learn more about astronomy and what it means to pursue a career in science. This event was part of the annual Girls’ Day, an initiative throughout Germany to encourage girls to learn more about occupational areas that are still male dominated. Even though the weather did not cooperate, the girls were very active and braved the cold and the rain to visit the roof telescope and launch their “rockets”. [more]

ALMA’s ability to see a “cosmic hole” confirmed

March 17, 2017
Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) successfully imaged a radio “hole” around a galaxy cluster 4.8 billion light-years away. This is the highest resolution image ever taken of such a hole caused by the Sunyaev-Zel'dovich effect (SZ effect). The image proves ALMA’s high capability to investigate the distribution and temperature of gas around galaxy clusters through the SZ effect. [more]

Probing the nature of the most luminous explosions

February 15, 2017
Supernovae are extremely bright stellar explosions – superluminous supernovae are even brighter. However, the nature of these most luminous explosions has remained a mystery. In a new study, MPA researchers now present their simulations of superluminous supernova spectra months and even years after the outbreak and show that they are very similar to gamma-ray bursts, another type of highly energetic explosions. In addition, the results point to very high masses of oxygen and magnesium, suggesting very massive progenitor stars that will use an exotic explosion mechanism rather than the standard neutrino-driven explosion believed to power most supernovae.

Cosmic lenses support finding on faster than expected expansion of the Universe

January 26, 2017
By using galaxies as giant gravitational lenses, an international group of astronomers including researchers at the Max Planck Institute for Astrophysics have made an independent measurement of how fast the Universe is expanding. The newly measured expansion rate for the local Universe is consistent with earlier findings. These are, however, in intriguing disagreement with measurements of the early Universe. This hints at a fundamental problem at the very heart of our understanding of the cosmos. [more]

Obituary to Heinz Billing

January 10, 2017
A pioneer in the development of electronic computing machines in Germany and one of the founders of gravitational wave astronomy is gone: on 4 January 2017, the astrophysicist Heinz Billing died at the age of 102. Billing was scientific member at the Max Planck Institute for Astrophysics in Garching from 1961 to '82. [more]

Fluctuations in extragalactic gamma rays reveal two source classes but no dark matter

December 19, 2016
Researchers from the Max Planck Institute for Astrophysics and the University of Amsterdam GRAPPA Center of Excellence just published the most precise analysis so far of the fluctuations in the gamma-ray background. They used more than six years of data gathered by the Fermi Large Area Telescope and found two different source classes contributing to the gamma-ray background. No traces of a contribution of dark matter particles were found in the analysis. The study was performed with an international collaboration of researchers and is published in the journal Physical Review D. [more]

Jérôme Guilet receives ERC starting grant

December 16, 2016
This week, the European Research Council and MPA-postdoc Jérôme Guilet signed the agreement for an ERC Starting Grant. The project funded will research exploding stars from first principles, in particular magnetars as engines of hypernovae and gamma-ray bursts. [more]
