Generic Mackey Formula for Higher Lusztig Functors
Higher Lusztig induction constructs a broad class of virtual smooth representations of parahoric subgroups in a $p$-adic group, serving as a natural generalization of classical Lusztig induction to the $p$-adic setting. This construction has important applications in the representation theory of p-adic groups. In this paper, we prove the Mackey formula for higher Lusztig induction in generic case, which generalizes a classic result of Lusztig in 1976. As an application, we give an irreducible d…

Lorentz invariance violation in the extragalactic propagation of ultra-high energy photons and in the development of showers in the Earth crust and atmosphere
We investigate the effects of Lorentz invariance violation (LIV) on photon interactions, considering both intergalactic propagation (Breit-Wheeler process) and atmospheric interactions (Bethe-Heitler process). By incorporating LIV into the theoretical framework, we analyze how it modifies key quantities such as the cross section, threshold energy, and mean free path of photons traveling through intergalactic space. In addition, we study its impact on extensive air showers initiated by high-ener…

Panchromatic characterization of the Y0 brown dwarf WISEP J173835.52+273258.9 using JWST/MIRI
Cold brown dwarf atmospheres are good training grounds for analyzing temperate giant planets. WISEP J173835.52+273258.9 (WISE 1738) is an isolated Y0 brown dwarf with a temperature between 350-400 K, at the T-Y transition. While its near-infrared spectrum has been studied, bulk properties and chemistry remain uncertain. We analyze new JWST MIRI medium-resolution spectra (5-18 micron), combined with near-infrared spectra (0.98-2.2 micron) from HST/WFC3 and Gemini/GNIRS, to better constrain WISE …

In a chain burrito restaurant with ongoing generic restaurant playlist. Plays the Mountain Goats' "This Year" in between Summer of 69 and Mr Brightside. Unexpected but welcome.

Wallis Annenberg, the Los Angeles philanthropist who provided generous financial support for a broad range of Southern California community projects that bear her name, has died at 86.
Annenberg died of lung cancer at her Los Angeles home, according to a statement posted to Instagram by Annenberg GenSpace, a research center she founded.
“I’ve never had a problem using the Annenberg name,” Ms. Annenberg told Vanity Fair in 2009.
“That’s who I am, and I’m happy to be that. I…

Dark Vector Boson Bremsstrahlung: New Form Factors for a Broader Class of Models
We explore the sensitivity of collider experiments to a broad class of GeV-scale dark vector models of new physics via production in proton and neutron bremsstrahlung and initial state radiation. This is achieved using a new physically motivated model for timelike vector form factors with generic charges for both protons and neutrons, which is fit to a variety of timelike and spacelike data with quantified uncertainties. The production model for both proton and neutron bremsstrahlung is applied…

BTW - The BeaverCon mentioned in that article does not refer to the traveling "convention dedicated to fostering connection, fun, and empowerment among female board gamers." I'm not making that up.
The more serious and scientific BeaverCon is a biennial meeting of wildlife and water conservation experts that hold workshops to demonstrate the power of Beavers.

Limits on WIMP-Scattering Cross Sections using Solar Neutrinos with Ten Years of IceCube Data
Although dark matter (DM) comprises 84\% of the matter content of the Universe, its nature remains unknown. One broad class of particle DM motivated by extensions of the Standard Model (SM) is weakly interacting massive particles (WIMPs). Generically, WIMPs will scatter off nuclei in large celestial bodies such as the Sun, thus becoming gravitationally bound. Subsequently, WIMPs can annihilate to stable SM particles, ultimately releasing most of their energy as high-energy neutrinos which escap…
