Ly$α$ in Compact Broad-Line Emitters, Including Little Red Dots, Is More Closely Linked to the Host Galaxy than to the Broad-Line Nucleus
JWST has found many faint broad-line AGN at $z>4$, but it is unclear whether the Ly$α$ we see from them comes from the accreting black hole or from its host galaxy.A full chemical network treatment of supermassive black hole seed formation from dark matter annihilation or decay
The recent discoveries of high-redshift quasars at $z\sim6-10.1$ present a challenge to conventional supermassive black hole (SMBH) formation scenarios: their central SMBHs are too large to have…Isophotal signatures of the brightest cluster galaxy - intracluster light transition
The distinction between brightest cluster galaxies (BCGs) and intracluster light (ICL) remains ambiguous, with inferred cluster properties depending strongly on the adopted definition and…Galactic-Scale Distribution of 10Be and Its Implications for the Early Solar System 10Be/9Be
Meteoritic inclusions indicate that the early Solar System contained a substantial abundance of the short-lived radionuclide 10Be.Long-range entangled criticality from coherent errors
We find that coherent error can induce a phase transition from the clean surface code phase into an extended long-range entangled critical regime with diverging Markov length.The STARfall pathway: forging intermediate-mass black holes through stellar collisions in dense star clusters
Intermediate-mass black holes (IMBHs, $10^2 < m_{\rm BH}/\mathrm{M}_{\odot} < 10^5$) are elusive objects bridging the gap between stellar-mass and supermassive black holes, whose origin remains…Revisiting the Missing Baryon Problem: Baryon Redistribution Across Halo Evolution
The baryon fraction provides a fundamental diagnostic of baryonic matter distribution within dark matter halos and the baryon cycle.Reconstruction of the conformal algebra from a critical groundstate on the (fuzzy) sphere
Recently, we found a method to reconstruct the dilatation operator (sphere Hamiltonian) from a regulated conformal field theory groundstate.H 0557$-$385: A Candidate Missing Link Between Radio-Quiet Seyferts and Young Radio Galaxies
The Seyfert 1 galaxy H 0557$-$385 (z = 0.034) has long been classified as radio-quiet on the basis of its radio-to-optical flux ratio, yet its radio properties are physically inconsistent with this…X-rays from Low-mass Active Galaxies in the Galaxy And Mass Assembly (GAMA) Survey
We present new Chandra observations of seven broad-line AGNs in low-mass galaxies ($M_\star < 5 \times 10^9\,M_\odot$) selected from the GAMA sample of Salehirad et al. (2022).He I $λ$10830 Resonant Scattering in M17: Toward a Diagnostic of Optical Depth and Gas Kinematics
The lower level of the He I $λ$10830 transition is metastable and therefore well populated.Estimating LuSEE-Night's Sensitivity to Cα Radio Recombination Lines
Carbon radio recombination lines (CRRLs) arising from the cold neutral medium (CNM) of the interstellar medium are potential foregrounds in the 1-50 MHz band that LuSEE-Night will observe from the…Entanglement-Aware Quantum Circuit Optimization through Globally Optimal Partitioning
We introduce a scalable framework for globally optimal quantum-circuit partitioning and entanglement-aware block resynthesis.Evidence for strong shocks in the ISM of small radio sources
Radio jets deposit energy into the interstellar medium of their host galaxies, and while a jet is still confined within the host it is expected to drive shocks through the gas.High-fidelity quantum gate learning via physics-informed neural networks
We propose a physics-informed neural network (PINN) approach for high-fidelity quantum gate learning in both one- and two-qubit systems.Factorized approximate inverse preconditioners in the tensor train format
We present a preconditioning pipeline that accelerates Tensor Train (TT) linear solvers for symmetric positive-definite problems.Interstellar and intergalactic medium in the ultraviolet band
This article presents an overview of key scientific challenges in the astrophysics and astrochemistry of the interstellar and intergalactic media.Liouvillian Kramers Degeneracy
The Kramers theorem generally guarantees the spectral degeneracy of time-reversal-invariant Hamiltonian operators with half-integer spin, underlying a variety of physical phenomena.Hardware-Aware Design and Layout Selection in Quantum Reservoir Computing for Insurance Claims Forecasting
Quantum reservoir computing (QRC) processes temporal information through quantum dynamics, but it remains unclear whether small QRC models can forecast real data competitively with classical models…Unital qubit channels are $3$-noisy
The algebraic and environmental characteristics of mixed unitary quantum operations are investigated.
