Quasars acting as Strong Lenses Found in DESI DR1

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Everett McArthur, Everett McArthur, , , | Summary: Quasars acting as strong gravitational lenses offer a rare opportunity to probe the redshift evolution of scaling relations between supermassive black holes and their host galaxies, particularly the $M_mathrmBH$–$M_mathrmhost$ relation. Using these powerful probes, the mass of the […]

Quasars acting as Strong Lenses Found in DESI DR1

Kavli Affiliate: Risa Wechsler | Summary:Quasars acting as strong gravitational lenses offer a rare opportunity to probe the redshift evolution of scaling relations between supermassive black holes and their host galaxies, particularly the $M_mathrmBH$–$M_mathrmhost$ relation. Using these powerful probes, the mass of the host galaxy can be precisely inferred from the Einstein radius $θ_mathrmE$. Using […]

Small Cancellation for Random Branched Covers of Groups

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:We construct a random model for an $n$-fold branched cover of a finite acceptable $2$-complex $X$. This includes presentation $2$-complexes for finitely presented groups satisfying some mild conditions. For any $λ>0$, we show that as $n$ goes to infinity, a random branched […]

BOOM and Babamul: a real-time, multi-survey, optical alert broker system operating at scale

Kavli Affiliate: Peter Graham| First 5 Authors: Theophile Jegou du Laz, Theophile Jegou du Laz, , , | Summary:With the arrival of ever higher throughput wide-field surveys and a multitude of multi-messenger and multi-wavelength instruments to complement them, software capable of harnessing these associated data streams is urgently required. To meet these needs, a number […]

The 2024 July 16 Solar Event: A Challenge To The Coronal Mass Ejection Origin Of Long-Duration Gamma-Ray Flares

Kavli Affiliate: Nicola Omodei | Summary:We present a multi-spacecraft analysis of the 2024 July 16 Long-Duration Gamma-Ray Flare (LDGRF) detected by the Large Area Telescope on the Fermi satellite. The measured >100 MeV $γ$-ray emission persisted for over seven hours after the flare impulsive phase, and was characterized by photon energies exceeding 1 GeV and […]

Realizing compatible pairs of transfer systems by combinatorial $N_infty$-operads

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:We investigate how the notions of pairings of operads of May and compatible pairs of indexing systems of Blumberg–Hill relate via the correspondence between indexing systems and $N_infty$-operads. We show that a pairing of operads induces a pairing on the associated indexing […]

Electric Accumulation of Millicharged Particles

Kavli Affiliate: Peter W. Graham | First 5 Authors: Asher Berlin, Asher Berlin, , , | Summary: A terrestrial population of millicharged particles that interact significantly with normal matter can arise if they make up a dark matter subcomponent or if they are light enough to be produced in cosmic ray air showers. Such particles […]

Electric Accumulation of Millicharged Particles

Kavli Affiliate: Peter Graham | Summary:A terrestrial population of millicharged particles that interact significantly with normal matter can arise if they make up a dark matter subcomponent or if they are light enough to be produced in cosmic ray air showers. Such particles thermalize to terrestrial temperatures through repeated scatters with normal matter in Earth’s […]
