Title: Cosmology with Cluster Number Counts
Speaker: Sebastian Grandis
Institution: Institute for Astro- and Particle Physics - University of 
Innsbruck
Date: Wednesday May 17, 2023
Time: 4:00PM
Location: Aula Conversi, Marconi Building (CU013), Dept. of Physics, 
Sapienza University

Abstract: The number counts of galaxy clusters are a powerful and 
independent cosmological probe. We review how several challenges in this 
experiment can be overcome by a combination of multi-wavelength data and 
hydrodynamical simulations. Specifically we will discuss how to 
empirically constrain the incompleteness and contamination fraction of 
cluster samples. We will also present an innovative method to quantify 
the accuracy of weak gravitational lensing inferred masses, as well as 
recent applications of this method. In the end, we will look ahead, to 
the opportunities and challenges present by future and starting 
cosmological surveys like eROSITA, Euclid and CMB stage 4.

*Hierarchical Black Hole Mergers: A Multi-Band Opportunity for
Gravitational Waves*

*Abstract*
With about a hundred binary black hole (BBH) mergers detected via
gravitational wave emission, our understanding of the darkest objects in
the Universe has seen unparalleled steps forward compared to previous
decades. While most of the events are expected to consist of
first-generation BHs formed from the collapse of massive stars, others
might be of a second or higher generation, containing the remnants of
previous BH mergers. A fundamental limit for hierarchical mergers comes
from the recoil kick imparted to merger remnants, which could result in the
ejection from the host star cluster. However, hierarchical mergers can
build up massive BHs and even form intermediate-mass black holes if the
host cluster is massive and dense enough, as in nuclear star clusters and
the most massive globular clusters. With their distinctive signatures of
higher masses and spins, hierarchical mergers offer an unprecedented
opportunity to learn about the densest systems in our Universe and to shed
light on the elusive population of intermediate-mass black holes. The next
years may bring hundreds of detections from hierarchical mergers with
multi-band events chirping from space-based to ground-based detectors,
promising a spectacular range of new science from stellar evolution to
cosmology.
