seminar Yann Gouttenoire Tuesday 27 June at 14:00
by Alberto Mariotti 26 Jun '23

26 Jun '23

Dear All, I'm happy to announce the seminar of Yann Gouttenoire (Tel Aviv University) next week Tuesday 27 June at 14:00 in the room G.1.03 - J. Sacton (Building G) at IIHE. Here the webpage of the event: https://indico.iihe.ac.be/event/1797/ Yann will talk about: Title: Primordial black holes from supercooled phase transition and implications for Pulsar Timing Arrays Abstract: Cosmological first-order phase transitions are said to be supercooled when the nucleation temperature is much smaller than the critical temperature. They are typical of potentials which feature nearly scale-invariance, for which the bounce action decreases only logarithmically with time. The phase transition takes place slowly and the probability distribution of bubble nucleation time is maximally spread. Hubble patches which get percolated later than the average are hotter than the background after reheating and potentially collapse into primordial black holes (PBH). In the first part of the talk, I will discuss the formation of PBH by supercooled phase transitions. In the second part, I will discuss the search for supercooled phase transitions in pulsar timing arrays and how it affects the search for PBH in LIGO-Virgo. Yann will be visiting us from Tuesday to Friday, so there will be plenty of time for discussions. Best, Alberto #---------------------------------------------------------------------# Alberto Mariotti Vrije Universiteit Brussel (VUB) https://we.vub.ac.be/HEPVUB Phone: +32 (0) 2 629 32 15 E-mail: alberto.mariotti(a)vub.be Address: Vrije Universiteit Brussel Physics Department Elementary Particles Research Group Pleinlaan 2, 1050 Brussels, Belgium #---------------------------------------------------------------------#

Hi All, please consider submitting an abstract/poster to the following conference (maybe with a bit of coordination among us to avoid multiple submissions). https://indico.desy.de/event/34916/ <https://indico.desy.de/event/34916/> The conference is quite broad with parallel sessions, but it is one of the most well-known conference in the field. The deadline is on Friday!!! In addition to the AstroPh&GW, there is also the Gravitation and Cosmology session, of which one of the convener is Fabrizio Rompineve (who advertises it again to me today at CERN ;) ).
