An alumna graduates!

A huge congratulations to former undergraduate group member Dr. Erica Hammerstein, who successfully defended her dissertation, titled “Population Studies of Tidal Disruption Events and Their Hosts: Understanding Host Galaxy Preferences and the Origin of the Ultraviolet and Optical Emission”. The NANOGrav results keep on coming out! The following papers were officially published in the past […]

So much has happened!

It has been over a year since posting a news item, but it has been a busy year. I will do bullet points of the most important stuff that has happened. The evidence for gravitational wave background is huge news. It was a huge effort to get there from a team I have loved being […]

NLST Meeting in Bothell, WA

I was in Bothell, WA right before AAS for a NASA LISA Study Team meeting. We put in some time thinking about the Science Ground Segment and the best ways for NASA to enable astrophysicists to extract science from LISA data. It’s really exciting to think about all the amazing stuff that will come from […]
