Ever wanted to learn about dark matter—the elusive particle that holds galaxies and galaxy clusters together? What about dark energy—the mysterious force that is causing our universe to expand at a continually increasing rate? If so, you’re in luck!

What these students did for their summer vacation: 2016 undergraduate research at KIPAC!

by Lori Ann White

Some things just go together. Hot dogs and mustard, smart phones and selfies, school and summer vacation. But science is a year-round proposition, and several undergrads didn't seem to mind forgoing their summer vacations to pursue a variety of research opportunities with members of KIPAC. (Protip: it’s never too soon to start thinking about next summer!)

Where are they now? -- An Interview with KIPAC alum Marusa Bradac

In the series, "Where are they now?" we check in with KIPAC alumni: where they are now, how they've fared since their days exploring particle astrophysics and cosmology at the Institute, and how their KIPAC experiences have shaped their journeys.

Leaving no stone unturned in the intense search for dark matter: focusing on the low-mass region with CDMS

By: Kristi Schneck

Over the past few years, several dark matter direct detection experiments have released results implying that dark matter may be hiding in an unexpected place.  These results suggest that dark matter particles may be ten times lighter than many physicists originally believed.  The Cryogenic Dark Matter Search (CDMS) collaboration, which includes many scientists from Stanford and KIPAC, has recently published several papers weighing in on the existence of this interesting type of dark matter particle.

Dark Concentration -- It Matters!

By Andrea Albert

In the hunt for dark matter, any information to help us narrow in on what to look for is key.  Miguel Sánchez-Conde (KIPAC and Stockholm University) and Francisco Prada (IFT/UAM, Madrid) have just published a crucial clue, concerning the concentration of dark matter halos, which are self-gravitating accumulations of dark matter that host systems like galaxies and galaxy clusters.  Their recent paper on “the flattening of the concentration-mass relation towards low halo masses and its implications for the annihilation signal boost” combines theoretical predictions with simulations to learn about Earth-mass to galaxy cluster-sized halos.  “The point of the paper is to put together the theory and the [simulations],” says Sánchez-Conde.
