We present a novel combination of the excursion-set approach
with the peak theory formalism in Lagrangian space and provide
accurate predictions for halo and void statistics over a wide range
of scales. The set-up is based on an effective moving...
Accretion-powered X-ray pulsars are neutron stars that accrete
matter from a companion star in a binary system, which exhibit
fascinating dynamics. The strong magnetic field of the neutron star
guides material onto the magnetic poles, which are...
I will present surprising observational results on the 3D
geometry of high-redshift star-forming galaxies based on Early
Release Science data from the James Webb Space Telescope. Using a
differentiable Bayesian model with Hamiltonian Monte Carlo,
I...
Tidal disruption events are luminous, transient flares that
occur when a star strays past the tidal radius of a supermassive
black hole (SMBH) and is torn apart by the SMBH's gravitational
field. These transients, predicted in the 70s, are now...
In our exciting era of experimental cosmology,
rapid developments in instrumentation and highly sensitive
superconducting detectors have provided a wealth of
arcminute-scale cosmic microwave background (CMB) data. These
measurements are transforming...
For more than 15 years, NANOGrav and other pulsar-timing array
collaborations have been carefully monitoring networks of pulsars
across the Milky Way. The goal was to find a tell-tale correlation
signature amid the data from all those pulsars that...
In this talk, I will present a method to remove the effects of
stellar activity from radial velocity measurements.
This method is based on a novel factorization of the measured
spectra to a sum of time independent eigen-spectra convolved with
small...
