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...

The Gaia mission and its data releases are driving a revolution in our understanding of the Milky Way and its constituents. In this talk, I will highlight a few of the results stemming from the analysis of the truly spectacular datasets produced so...

The Basic Plasma Science Facility (BaPSF) at UCLA is a US national collaborative research facility sponsored by DOE and NSF for studies of fundamental processes in magnetized plasmas. The centerpiece of the facility is the Large Plasma Device (LAPD)...

The Teukolsky master equations describe the linear behavior of extremal perturbations of the Kerr black hole family.

In this talk, we focus on separable solutions to the Teukolsky equations, for which superradiance and trapping phenomena can be...

Macroscopic Dark Matter (MDM) refers to an entire class of dark matter candidates, also commonly dubbed as Macros, consisting of composite objects characterized by a large mass and geo- metric cross-section. A possible signature of MDM is the...

Dynamics provides a powerful tool to unify the various components of a planetary system. By studying the interactions between these components, it is possible to unveil a system’s evolutionary history and to constrain what is and what is not missing...

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

In the Solar system, the planets follow orbits that are nearly aligned with the Sun's equatorial plane. What about planets around other stars? Many techniques are available to measure the obliquities of planet-hosting stars, ranging from an effect...
