Normalizing Flows (NF) are bijective maps from the data to a
Gaussian (normal) distribution or viceversa. In contrast to other
generative models they are lossless and provide data likelihood via
the Jacobian of the transformation. I will first...
The Event Horizon Telescope (EHT) has produced images of both
total intensity and polarized radiation from plasma around the
supermassive black hole in M87 on event horizon scales.
In this talk, I will discuss what these images tell us about
the...
Abstract 1: Upcoming cosmological surveys will measure the
large-scale distribution of galaxies at the subpercent level. In
order to extract unbiased cosmological data while retaining
valuable small-scale information, we need highly accurate
models...
The NASA Kepler mission has provided its final planet candidate
catalogue, the K2 mission has contributed another four years’ worth
of data, and the NASA TESS mission has been churning out new planet
discoveries at a rapid pace. The demographics of...
It was recently proposed that extragalactic fast radio bursts
can be produced during magnetic reconnection in a compressed
current sheet of the magnetar wind, triggered by the strong fast
magnetosonic pulse produced by a magnetar flare. The current...
Direct-imaging surveys are gradually filling in the parameter
space of massive substellar objects (brown dwarfs and giant
exoplanets) at wide orbital separations (>1 au). As
statistically large samples of such objects are built up, we can
begin to...
Recent advances in large-scale structure (LSS) theory have
opened up new avenues for probing fundamental physics with the
cosmic web. Future galaxy surveys will soon map the Universe with
unprecedented sub-percent precision. I will present tools...
The Large Hadron Collider (LHC) at the CERN laboratory is the
world's most powerful particle accelerator. The LHC has had a
successful and highly productive Run 2 era (2015-2018), colliding
protons with a center-of-mass energy of 13TeV, and breaking...
EDGES reported the first evidence of star formation in the
high-redshift Universe (z~18) in 2018 (Bowman et al, 2018;
hereafter B18). The extraordinary depth and flattened profile of
the reported absorption feature in the sky-averaged 21 cm
spectrum...
