CfA Colloquium
Weekly astrophysics research colloquium talks from the Harvard-Smithsonian CfA.
Just interesting stuff.
The Harvard-Smithsonian Center for Astrophysics colloquium channel: weekly research talks from Phillips Auditorium, webcast in 1080p, covering whatever is current in the astrophysics research community — particle physics at the redshift frontier, CMB cosmology, planetesimal disruptions. Uploads have slowed in the last few months, but the archive is 360+ talks of frontier astrophysics for free.
