Astrophysics and Cosmology
The Astrophysics and Cosmology group at Northeastern University is leading cutting-edge research into the nature of the universe, including dark energy, large-scale structure, galaxy clusters, black holes across all mass scale and neutron stars, dark matter searches, and MeV gamma-ray observations.
Members
-
Prof. Aramaki’s group develops and utilizes sensitive detectors in underground and outer space (balloon/satellite) for dark matter searches and astrophysical observations (SuperCDMS, GAPS, and GRAMS).
-
Prof. Blazek’s group probes the cosmological model using analytic methods, simulations, and maps made with the largest galaxy surveys (DES and LSST).
-
Prof. Lin’s group utilizes ground- and space-based observatories to carry out multi-messenger study of high-energy transient signals such as tidal disruption of stars by supermassive black holes and gravitational wave events (Chandra, XMM-Newton, and HST).
-
Prof. McCleary’s group conducts balloon- and ground-based observations of gravitational lensing by galaxy clusters to understand their dark matter and astrophysics (SuperBIT and LoVoCCS).

The proposed NASA budget cuts would decimate American science, an expert says
Trump is calling for a 25% slash to NASA’s budget and according to Jacqueline McCleary, assistant professor of physics, the cuts will have a larger impact then proposed, including hurting America’s ability to maintain its position as a leader in tech and space exploration. -
Using a Novel Balloon-Borne Technology to Probe Deeper into our Dark Universe
NASA has awarded Northeastern and partners a prestigious grant to launch a particle detector into earth’s upper atmosphere. How can we better understand vital questions about the unseeable dark matter that seems to constitute much of the vast universe around us? And how can we capture the faintest yet most information-rich signals from distant astrophysical […] -
This Northeastern physicist is revolutionizing astronomy with unprecedented dark matter mapping through space observatory in Chile
A new astronomical observatory nearing completion atop a desert mountain in northern Chile will reveal the workings of the universe as never before. It might even revolutionize our understanding of the mysterious forces shaping the cosmos, such as dark energy, says Northeastern assistant physics professor Jonathan Blazek. With a telescope as wide as a tennis […] -
