Primordial black holes are a fascinating family of black holes that may have formed in the early universe and are considered a potential candidate for the dark matter. After briefly reviewing their formation mechanism and evolution throughout cosmic history, we explore their detectability via gravitational waves. In particular, we focus on signals emitted both during their formation and from the merger of associated primordial binaries. Finally, we highlight potential smoking-gun signatures that could probe their existence in future gravitational wave observatories, such as the Einstein Telescope and LISA. | Primordial black holes are a fascinating family of black holes that may have formed in the early universe and are considered a potential candidate for the dark matter.

This page records the schedule, titles and abstracts of the JHU/STScI CAS Astrophysics Wine & Cheese Series in Fall 2025.
Wine and Cheese sessions with one speaker will have a 50 minute talk with 10 minutes for questions. Sessions with two speakers will have two 25 minute talks, each with 5ish minutes for questions.(Since when have you ever seen a question session cut short if everyone is interested?)

Evolution of Supermassive Black Holes and their Host Galaxies at z > 6 with JWST
Clues on the formation of supermassive black holes may be found in the properties of their host galaxies and mass relations with cosmic time. We will present results from JWST programs based on the Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs) at z > 6. The detection of the host galaxies enables the first assessment of the intrinsic ratio between black hole mass and stellar mass with consideration of selection effects and measurement uncertainties. Furthermore, new results will be presented on the detection of lower mass black holes, which highlight a large population of undermassive black holes at z > 6 just beginning to be tapped by JWST.

Primordial Black Holes: a Gravitational Wave Quest
Primordial black holes are a fascinating family of black holes that may have formed in the early universe and are considered a potential candidate for the dark matter. After briefly reviewing their formation mechanism and evolution throughout cosmic history, we explore their detectability via gravitational waves. In particular, we focus on signals emitted both during their formation and from the merger of associated primordial binaries. Finally, we highlight potential smoking-gun signatures that could probe their existence in future gravitational wave observatories, such as the Einstein Telescope and LISA.
