How Bright is the Radio Sky? (We Don’t Know) (yet)

4:00 pm (CDT)Hawking Auditorium

Speaker: Jack Singal (University of Richmond)Host: Doojin Kim

The actual level of diffuse radio emission on our sky is surprisingly uncertain.  Almost all investigations that depend on understanding the radio sky, including cosmic microwave background and 21 cm cosmology foregrounds, rely on just one measurement – the 408 MHz Haslam map from the 1980s, which traces its absolute calibration to highly uncerta... read more  »

Black Holes in the Early Universe

4:00 pm – 5:00 pm (CDT)Hawking Auditorium

Speaker: Dan Hooper (University of Chicago)Host: Doojin Kim

Cosmology textbooks typically assume that the early universe was dominated by relativistic particles. But if even a relatively small number of black holes were created after inflation, they would make up an increasingly large fraction of the total energy density as space expands. I’ll argue that it is well-motivated to scenarios in which the early uni... read more  »
