Deep learning (DL) methods have demonstrated great potential for extracting rich non-linear information from cosmological fields, a challenge that traditional summary statistics struggle to address. Most of these DL methods are discriminative models...

The assembly of planetesimals, a key step in the formation of planets, remains riddled with questions. In particular, there is ambiguity regarding the environments in which dust accumulations at the mid-planes of protoplanetary disks become unstable...

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 high-Lundquist-number plasmas, reconnection proceeds via onset of tearing, followed by a non-linear phase when plasmoids continuously form, merge, and are ejected from the current sheet (CS). This process is understood in fully ionized...

Abstract: The Fractional Quantum Hall effect is one of the most fundamental phenomena of quantum physics. Under a very large magnetic field, and at fractional filling of a Landau level, when electrons are “supposed” (by simple band theory) to form a...

Rest-frame UV spectra play a key role in the understanding of massive stellar populations, chemical evolution, feedback processes, and reionization. Indeed, in the current JWST era, the UV spectroscopic frontier has been pushed to higher redshifts...

Abstract: LUX-ZEPLIN (LZ) is a direct detection dark matter experiment currently being operated at the Sanford Underground Research Facility (SURF) in Lead, South Dakota. The experiment utilizes a dual phase time projection chamber (TPC)  to...
