  • Of the13 proposals which were approved out of a pool of 106 for the highly selective JWST Director's Discretionary Early Release Science Program (DD-ERS), two of the programs contain Astronomy's very own research scientists and professors including Sylvain Veilleux, Co-PI on the project entitled, "Analyzed with a Powerful New PSF Decomposition and Spectral Analysis Package" and Mark Wolfire, one of the lead investigators of another proposal studying, "Radiative Feedback from Massive Stars as Traced by Multiband Imaging and Spectroscopic Mosaics." These early release programs will be the first to access JWST and obtain unprecedented data! Too view other early release programs selected head to the STScI webpage.

October 2017

  • UMD research scientists win the Aspen Institute Italia Award 2017 for their pioneering research on black holes and galaxy formation. The award-winning paper, "Wind from the black hole accretion disk driving a molecular outflow in an active galaxy," was led by assistant research scientist Francesco Tombesi, and co-authored by research scientist Marcio B. Meléndez Hernández and professors Sylvain Veilleux, and Christopher S. Reynolds. Featured on the cover of Nature, the paper discusses how the wind of black holes affect the evolution of their host galaxies. Congratulations Francesco, Marcio, Sylvain and Christopher!
  • University of Maryland researcher's participated in the historic detection of gravitational waves, electromagnetic signals and observed a kilonova in unprecedented detail as they witnessed two neutron star mergers! Alongside other scientists across the country, members of the Astronomy Department including Eleonora Troja (assistant research scientist and lead author of the Nature paper), Sylvain Veilleux (professor), Alexander Kutyrev (associate research scientist) and Goddard affiliates Brad Cenko (adjunct assistant professor) and Leo Singer (post-doctoral associate), took part in the study and capture of this incredible phenomenon. To hear more about this extraordinary event refer to the article from The Baltimore Sun and the press release on the CMNS website. Congratulations to our scientists!
