Michael Jaramillo | Positional Covariance in Multi-Wavelength Astronomy

Michael Jaramillo

By Michael Jaramillo ’17 B.S. Astrophysics I had the opportunity to work under the direction of Dr. Douglas Clowe. His research is on determining the dark matter distribution in galaxy clusters through weak gravitational lensing. One of my main jobs as his intern was to make sure the images of […]

Clowe, Santana Probe First Signs of Self-interacting Dark Matter

This image from the NASA/ESA Hubble Space Telescope shows the rich galaxy cluster Abell 3827. The strange blue structures surrounding the central galaxies are gravitationally lensed views of a much more distant galaxy behind the cluster. Observations of the central four merging galaxies have provided hints that the dark matter around one of the galaxies is not moving with the galaxy itself, possibly implying dark matter-dark matter interactions of an unknown nature are occurring.

For the first time, dark matter may have been observed interacting with other dark matter in a way other than through the force of gravity. Observations of colliding galaxies made with ESO’s Very Large Telescope and the NASA/ESA Hubble Space Telescope have picked up the first intriguing hints about the […]

Sky and Telescope Quotes Clowe on New Look at Dark Matter, Bullet Cluster

Dr. Douglas Clowe

Sky and Telescope quotes Dr. Douglas Clowe, Associate Professor of Physics & Astronomy, in an article on “How Slippery is Dark Matter?” “Dozens of galaxy cluster collisions confirm that dark matter particles probably slip right past each other within messy cluster mergers,” writes Monica Young. “The existence of dark matter […]

What Role Do Dark Matter and Dark Energy Play in Universe?

What Role Do Dark Matter and Dark Energy Play in Universe?

By Stephanie Dutchen From Perspectives Peer through a telescope and you’ll see a night sky filled with galaxies, gas and dust clouds, planets, pulsars, black holes, and ever more beautiful and strange objects. But this cosmic light show only reveals part of the picture. When you add the masses of […]
