Atomic collapse in gapped graphene: lattice and valley effects

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Xiaotai Wu, Wen-Sheng Zhao, Yuhua Cheng, Yue Hu | Summary: We study the atomic collapse phenomenon in $K$ and $K’$ valley of gapped graphene. Bound states induced by Coulomb impurity in the gap turn into atomic collapse resonances as the charge increases beyond the supercritical […]

Theoretical Predictions for the Inner Dark Matter Distribution in the Milky Way Informed by Simulations

Kavli Affiliate: Lina Necib | First 5 Authors: Abdelaziz Hussein, Lina Necib, Manoj Kaplinghat, Stacy Y. Kim, Andrew Wetzel | Summary: We build a theoretical range for the Milky Way’s (MW) inner dark matter (DM) distribution informed by the FIRE-2, Auriga, VINTERGATAN-GM, and TNG50 simulation suites assuming the canonical cold dark matter (CDM) model. The […]

Early r-process Enrichment and Hierarchical Assembly Across the Sagittarius Dwarf Galaxy

Kavli Affiliate: Anna Frebel | First 5 Authors: Xiaowei Ou, Alexander Yelland, Anirudh Chiti, Anna Frebel, Guilherme Limberg | Summary: Dwarf galaxies like Sagittarius (Sgr) provide a unique window into the early stages of galactic chemical evolution, particularly through their metal-poor stars. By studying the chemical abundances of stars in the Sgr core and tidal […]

BlackTHUNDER — A non-stellar Balmer break in a black hole-dominated little red dot at $z=7.04$

Kavli Affiliate: Debora Sijacki | First 5 Authors: Xihan Ji, Roberto Maiolino, Hannah Übler, Jan Scholtz, Francesco D’Eugenio | Summary: Recent observations from JWST have revealed an abundant population of active galactic nuclei (AGN) and so-called “Little Red Dots” (LRDs) at $2lesssim z lesssim 11$, many of which are characterized by V-shaped UV-to-optical continua with […]

On the equivalence between galaxy angular correlation function and power spectrum in constraining primordial non-Gaussianity

Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Yue Nan, Masahiro Takada, , | Summary: We investigate the angular power spectrum ($C_ell)$ and angular correlation function ($w(theta)$) of galaxy number density field in the presence of the local-type primordial non-Gaussianity (PNG), explicitly accounting for the integral constraint in an all-sky survey. We show […]

Introducing the AIDA-TNG project: galaxy formation in alternative dark matter models

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Giulia Despali, Lauro Moscardini, Dylan Nelson, Annalisa Pillepich, Volker Springel | Summary: We introduce the AIDA-TNG project, a suite of cosmological magnetohydrodynamic simulations that simultaneously model galaxy formation and different variations of the underlying dark matter model. We consider the standard cold dark matter model and five […]

The centimeter emission from planet-forming disks in Taurus

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Antonio Garufi, Carlos Carrasco-Gonzalez, Enrique Macias, Leonardo Testi, Pietro Curone | Summary: The last decade has witnessed remarkable advances in the characterization of the (sub-)millimeter emission from planet-forming disks. Instead, the study of the (sub-)centimeter emission has made more limited progress, to the point that only […]

GLIMPSE: An ultra-faint $simeq$ 10$^{5}$ $M_{odot}$ Pop III Galaxy Candidate and First Constraints on the Pop III UV Luminosity Function at $zsimeq6-7$

Kavli Affiliate: Anna Frebel | First 5 Authors: Seiji Fujimoto, Rohan P. Naidu, John Chisholm, Hakim Atek, Ryan Endsley | Summary: Detecting the first generation of stars, Population III (PopIII), has been a long-standing goal in astrophysics, yet they remain elusive even in the JWST era. Here we present a novel NIRCam-based selection method for […]
