Measurements of pulsar acceleration reveal Milky Way’s dark matter density
Researchers have used pulsar measurements to help uncover new information about the density of dark matter in our home galaxy. In a new study led by RIT Associate Professor Sukanya Chakrabarti, researchers have now obtained the first direct measurement of the average acceleration taking place within the Milky Way.

A 'Ghost Galaxy' May Have Given the Milky Way Its Signature Swirl
Though direct observational evidence of Antlia 2 was not obtained until last year, one scientist has had a decade-long hunch that it was there. Sukanya Chakrabarti, an astrophysicist at RIT predicted in 2009 that an object packed with dark matter was causing tidal effects at the edge of the Milky Way.

Milky Way Collided with Dark-Matter Dominated Galaxy Less Than Billion Years Ago
Sci-News features new research, led by RIT, that shows the collision of the recently-discovered dwarf galaxy Antlia 2 with the Milky Way Galaxy hundreds of millions of years ago is responsible for ripples in the Milky Way’s outer gas disk.

Scientists detected signs of our Milky Way colliding with another 'ghost' galaxy
Antlia 2, the "ghost of a galaxy" orbiting the Milky Way, is a dark horse in more ways than one. Not only is it so faint it was only just discovered last year, it may now be responsible for curious ripples in the hydrogen gas that makes up the Milky Way's outer disc.

New evidence shows crash with Antlia 2 gave the Milky Way the ripples in its outer disc
The newly-discovered dark dwarf galaxy Antlia 2’s collision with the Milky Way may be responsible for our galaxy’s characteristic ripples in its outer disc, according to a study led by Assistant Professor Sukanya Chakrabarti. The Antlia 2 dwarf galaxy was discovered from the second data release of the European Space Agency’s Gaia mission, which aims to chart a three-dimensional map of our galaxy.
