Re: the last boost. While the thread is inspired by US universities, it _absolutely_ applies to Canadian post-secondary institutions too.

Radio emission from flaring stars and brown dwarfs
Aims. With the aim to reveal the effects of the magnetic field to the multi-band activity of dwarf stars, we search for associated radio emission for an extensive list of 14 915 brown dwarfs and 15 124 flaring stars. Methods. We utilised the first and second epoch catalogues and radio maps from all three epochs of the VLASS, supplemented with X-ray catalogues based on observations by the ROSAT, eROSITA, and XMM-Newton space telescopes, and 2-minute cadence optical light curves from the TESS mis…

3C 403: a candidate neutrino-emitting radio galaxy
3C 403 is a well known FRII radio galaxy, whose jets extend up to the kpc scale. In this letter, we present its identification as the second most significant source among the more than 150 inspected using the 15-year neutrino dataset of the ANTARES Collaboration, possibly making it the first radio galaxy with neutrino emission. Following the previous association of blazars with netrinos events, we aimed at studying the jet properties and its possible role in neutrino production. We collected mu…

I believe this is the first coverage to acknowledge that Lurie’s budget seems to treat a “temporary” new jail as permanent
“representatives from the People’s Budget Coalition lined the second and third floor balconies of City Hall’s rotunda. They held yellow posters reading ‘No new jail! No cuts!’ referring to the continued funding for the jail annex in San Bruno.”

Hundreds protest S.F. budget cuts, packing City Hall chambers
Protesters unfurled banners in the San Francisco City Hall rotunda reading "Stop cuts" that were quickly taken down by sheriff's deputies.

A conjectural generalization of the Briançon-Iarrobino Conjecture
We conjecturally generalize the Conjecture by Briançon and Iarrobino on the most singular points of the Hilbert scheme of a tetrahedral number of points in $\BA^3$ by introducing the notion of \textit{locally-maximal singularity}. The formulation of this conjecture is based on the shape of the ideals via a picturesque pattern. It also generalizes the conjectural necessary condition for the most singular points, suggested by the second-named author in \cite{Rezaee-23-Conjectures}, restricted to…

Signatures of BH seeding on the $\mathrm{M_{\displaystyle \bullet}}-σ$ relation: Predictions from the BRAHMA simulations
The James Webb Space Telescope (JWST) has identified a large population of supermassive ($10^6$-$10^8~\mathrm{M}_\odot$) black holes (BHs) in the early universe ($z \sim 4$-$7$). Current measurements suggest that many of these BHs exhibit higher BH-to-stellar mass ratios than local populations, opening a new window into the earliest stages of BH-galaxy coevolution and offering the potential to place tight constraints on BH seeding and growth in the early universe. In this work, we use the BRAHM…

Detectors and Electronics for the CBM experiment at FAIR
The Compressed Baryonic Matter (CBM) experiment is a next-generation heavy-ion experiment under development at the future FAIR facility in Darmstadt, Germany. It is designed to explore the QCD phase diagram at high net-baryon densities with unprecedented precision. Operating in fixed-target mode with a continuous beam of up to 11 AGeV for heavy ions and 26 GeV for protons, CBM will investigate rare probes such as multi-strange hyperons, hypernuclei, and dileptons, aiming to identify signatures …

Mapping the gas density with the kinematic Sunyaev-Zel'dovich and patchy screening effects: a self-consistent comparison
The secondary anisotropies of the cosmic microwave background (CMB) provide a wealth of astrophysical and cosmological information. Pairing measurements of the CMB temperature map obtained by DR5 of the Atacama Cosmology Telescope (ACT) with the large-scale structure imaging survey conducted by the Dark Energy Spectroscopic Instrument, DECaLS DR9, we investigate two effects that are sensitive to the gas density $τ$: kinematic Sunyaev-Zel'dovich (kSZ) and `patchy screening' (also known as `anis…

Schwarzschild Black Holes Immersed in Born-Infeld Magnetic Fields and Their Observational Signatures
We investigate the influence of Born-Infeld (BI) nonlinear electrodynamics on magnetic field configurations, photon orbits, and black hole shadows for Schwarzschild black holes immersed in magnetic fields. Assuming that the BI magnetic fields are asymptotically uniform and aligned with the polar axis, we solve the nonlinear magnetic field equations numerically using pseudospectral methods. Our analysis shows that nonlinear electromagnetic effects become prominent near the event horizon, particu…

EEG Foundation Challenge: From Cross-Task to Cross-Subject EEG Decoding
Current electroencephalogram (EEG) decoding models are typically trained on small numbers of subjects performing a single task. Here, we introduce a large-scale, code-submission-based competition comprising two challenges. First, the Transfer Challenge asks participants to build and test a model that can zero-shot decode new tasks and new subjects from their EEG data. Second, the Psychopathology factor prediction Challenge asks participants to infer subject measures of mental health from EEG da…
