Astronomy Seminar: "Understanding the Cosmological Evolution of Galaxies with Intensity Mapping"

Jason Sun (Caltech)
- See Zoom link below

The intensity mapping (IM) technique has been devised as a powerful tool to investigate the large scale structure and galaxies, alternative and complementary to the more traditional means relying on…

Past Astro Seminars



Astronomy and Astrophysics Seminar: Exploring the universe with gravitational waves

Valeri Vardanyan (IPMU Tokyo)
- Zoom

In this talk, I will present recent results about gravitational wave cosmology. I will argue that the spatial clustering of gravitational wave sources, when cross-correlated with galaxy catalogues,…



Astronomy and Astrophysics Seminar: The next frontier in gravitational wave cosmology

Jose Maria Ezquiaga (Chicago)
- Zoom

Gravitational waves (GWs) are reshaping our understanding of the universe, and the more exciting discoveries are yet to come. In the next observing runs we will observe hundreds to thousands of events per…



Astronomy and Astrophysics Seminar: Cosmological Information in Forward Modeling of Biased Tracers

Giovanni Cabass (IAS).
- DRL 4C6

I discuss how much information on cosmological parameters can be extracted from a perturbative bias model at the field level after marginalizing over initial conditions, compared with summary…



Astronomy and Astrophysics Seminar: Seeking solutions for the Hubble tension

Meng-Xiang Lin (Chicago)
- Zoom

Although the $\Lambda$CDM model has been remarkably successful in explaining a wide range of observational data, the model does not reconcile distance-redshift measurements when anchored at low redshift…
