How Magnetic Fields Regulate Cooling and Mixing in Turbulent Radiative Mixing Layers
Turbulent radiative mixing layers (TRMLs) are expected wherever hot and cold gas move past one another, including in the solar corona, galactic winds, and cold filaments in galaxy clusters.Discovery of an isolated RELHIC Candidate: J1351+0039
We report the discovery of J1351+0039, a new isolated dark galaxy candidate identified through a blind HI survey with the Five-hundred-meter Aperture Spherical radio Telescope (FAST), combined with…Exceptional Gamma-Ray Flaring Activity of the Blazar S4 0954+65 in Early 2025
S4 0954+65 (4FGL J0958.7+6534) is a TeV-detected blazar at a redshift of $z = 0.3694 \pm 0.0011$, classified as an intermediate-synchrotron-peaked BL Lac object.PAHSPECS: JWST/MIRI Spectroscopy of PAHs at Cosmic Noon
The physical conditions of the interstellar medium (ISM) are thought to differ greatly at high redshifts compared to local galaxies.Two-rung ladder: $H_0$ from Tip of the Red Giant Branch and geometric anchors alone
We infer the Hubble constant $H_0$ from the ~400 Extragalactic Distance Database hosts with a tip of the red giant branch (TRGB) distance, calibrated on the geometric anchors of the Large Magellanic…The JWST and ALMA view of local dwarf Pox 186: Evidence of stripped binaries driving a hard radiation field and little cold molecular gas resulting in high star-formation efficiency
We present a JWST mid-infrared (MIR) view of Pox 186, one of the best local analogs of reionization-era galaxies based on its extreme properties in the ultraviolet, optical, and far-infrared (FIR).CERIDWEN: Fast and Flexible GPU-Accelerated Stellar Population Inference
JWST has increased both the number of high-redshift galaxies with high-quality spectral energy distributions (SEDs) and their information content.Breaking the Blend: A multi-tracer kinematic decomposition method for IFS data applied to disentangling the AGN outflow and circumnuclear ring in NGC 5728 with JWST
Integral field spectroscopy (IFS) of the central kiloparsecs of active galactic nuclei (AGN) reveals a mixture of spatially coincident emission from star-formation and AGN feedback exciting the…The geometric origin of the thermal eccentricity law
The distribution $f(e)=2e$ is commonly referred to as the `thermal eccentricity distribution' of Keplerian binaries.Igniting Galaxy Formation in the Postreionization Universe, II: Nature versus Nurture
Although the ultraviolet background from reionization is thought to conspire against the smallest halos, some gas-rich halos in the post-reionization Universe still form stars.A Self-Consistent Jeans Analysis of the Milky Way Rotation Curve
Jeans-based measurements of the Milky Way (MW) rotation curve (RC) have revealed a declining outer RC.Hidden in the Halo: New Diffuse Star Clusters in the M82 Starburst with JWST
Diffuse star clusters (DSCs) occupy a poorly explored region of the size-luminosity plane between classical globular clusters (GCs) and dwarf galaxies.TRICEPS. I. Tracing cold gas, dust, and stars at sub-kpc scales in massive star-forming galaxies at z = 4-5
We introduce the TRICEPS (Tracing Resolved Ionized Carbon Emission in Primeval Systems) survey.Saturation Mechanism of Cosmic Ray Streaming Instabilities with a Shell Distribution
Cosmic rays (CRs) drive galactic winds and regulate galaxy growth while contributing to heating the central cooling plasma in dense galaxy clusters, making the nonlinear saturation of the…SN Helios: A Multiply Imaged Type II Supernova Opening Time-Delay Cosmography beyond redshift of 3
We report the discovery and spectroscopic confirmation of SN Helios, a strongly lensed, multiply imaged Type II supernova (SN) at $z=3.34$ behind the galaxy cluster RXC J0018.5+1626.A tidal disruption event in a quasar at redshift 7.19
We report a long-lived nuclear transient in GNz7q, a red quasar at $z=7.19$ powered by a $\sim3\times10^{7}\,M_\odot$ black hole and hosted by a compact, dusty starburst galaxy.Collisional excitation of E- and Z-ethanimine to model cold molecular clouds
Ethanimine is a prebiotically relevant complex organic molecule that has been proposed as a key precursor of amino acids in the interstellar medium.Breaking the AGB Color Degeneracy with Variability and H$_2$O: A Consistent Picture of AGB Chemistry, Dust, and the J-Region Across Environments
Resolved asymptotic giant branch (AGB) populations present many observational puzzles.The JWST Proto-PAH project. Computational modeling of the emission carriers
The infrared spectra of many carbon-rich post-asymptotic giant branch stars are dominated by emission features from aromatic and aliphatic hydrocarbons, but the chemical structure of the carriers…The JWST Proto-PAH project: Aromatic backbones with extensive aliphatic substitution account for both the aromatic and aliphatic emission
We find that the aromatic and aliphatic emission bands in four carbon-rich post-asymptotic giant branch stars with class D emission arise from a single carrier population: extensive aliphatic…
