Quantifying the decline in CO(2-1) intensity around PHANGS-HST star clusters: Constraints on molecular gas dispersal, stellar feedback, and cluster formation efficiency
We combine the largest survey of star clusters in nearby galaxies to-date, PHANGS-HST, with maps of molecular gas maps from PHANGS-ALMA to constrain the efficiency of cluster formation and the…Dynamical Evolution of The Open Clusters Collinder 110 and NGC 2477
Using Gaia DR3 photometric and astrometric data, we identified the likely members of the open clusters Collinder 110 and NGC 2477, and derived their astrophysical and dynamical parameters.SLICE: Unveiling the Multi-Component Merging Core of SPT-CLJ1150-2805 Through Strong-Lensing Mass Modelling
We present a new strong-lensing and X-ray mass model of the merging galaxy cluster SPT-CLJ1150-2805 ($z=0.383$), combining JWST NIRCam, HST, Chandra, and VLT/MUSE data to robustly decompose its…The AURORA Survey: Determining the Production Mechanism for OI $\mathbf{λ8449}$ Emission in Star-forming Galaxies at Cosmic Noon
We analyze deep JWST/NIRSpec observations of 58 star-forming galaxies at $1.3< z <4.8$ in the AURORA survey to investigate the origin of the permitted OI $λ8449$ emission feature.Recurrent double-peaked $γ$-ray sub-flares in PKS 1424-418
We report a hint of recurrent double-peaked $γ$-ray sub-flares in PKS~1424--418 during two similar major active epochs, MJD 56117--56498 and MJD 59669--59978.Uber-calibration-based Two-level Radial-velocity Zero-point Correction for APOGEE
APOGEE delivers high-resolution, near-infrared spectroscopy and highly precise radial velocities (RVs), with extensive repeat observations spanning more than a decade.High-z galaxies with the JWST and the ELT: Toward Ever-finer Detail
The exploration of the early Universe is being transformed by the James Webb Space Telescope (JWST), which delivers unprecedented angular resolution at infrared wavelengths and opens a unique window…Mass-Dependent Dark Matter Deficit from Inelastic Scattering
Recent stellar-kinematic and neutral-hydrogen observations indicate a dark matter deficit within the central tens of kiloparsecs of nearby galaxies that grows systematically with stellar mass…Stellar Collisions from Self-consistent Stellar Dynamics Around Growing Supermassive black Holes
The centers of galaxies harbor the densest stellar environments, where a massive black hole (MBH) accelerates stars to such high velocities that direct collisions can result in high-energetic…Binary-pulsar Timing: A 3D Solar-System Accelerometer and Unknown-Source Probe
The acceleration of the Solar System barycenter (SSB) offers a unique precision probe of the local gravitational environment, enabling searches for otherwise invisible gravitating sources such as…Optical spectropolarimetry of extreme H$α$ line profiles in seven active galactic nuclei
Some active galactic nuclei (AGNs) are known to show extremely asymmetric broad Balmer lines, with their main peak redshifted or blueshifted by thousands of km s$^{-1}$, severely challenging our…Metal-Poor Stars as Metal-Rich Impostors via Planet Engulfment
Planet engulfment leads to planetary mass accretion and angular momentum deposition into the stellar envelope.A Census of Stellar-mass Black Holes in the Milky Way with POPKIN. I. Isolated Black Holes
Gravitational-wave observations have revealed hundreds of stellar-mass black holes, yet only about two dozen are known in the Milky Way, almost all in binaries.JWST Observations of the Metal-poor T Dwarf WISEA J155349.96+693355.2: The First Brown Dwarf Associated with the Gaia-Enceladus Milky Way Substructure
We present JWST NIRSpec and MIRI observations of the metal-poor T dwarf WISEA J155349.96+693355.2.Probing binary supermassive black hole in quasars tough spectropolarimetry
Nearly all galaxies are believed to host a supermassive black hole at their center.Potential binary supermassive black holes in Markarian 231 as a scientific case for the spectropolarimeter POLLUX
It is now widely accepted that a supermassive black hole (SMBH) resides in the core of nearly every galaxy.Spatial segregation as the origin of anisotropic satellite quenching in haloes and beyond
Satellite galaxies in massive halos are seen to be preferentially quenched along the major axes of their central galaxies.Galaxy And Mass Assembly (GAMA): The Most Isolated GAMA Galaxies
While galaxies generally live in clusters and groups, particularly small groups, or other structures such as walls or filaments, some galaxies appear relatively `isolated', i.e. lacking in close…AGN winds and outflows: from accretion-disc scales to the host galaxy
Ultra-fast outflows (UFOs), launched from the inner accretion disc in active galactic nuclei (AGN), are among the prime candidates for driving AGN feedback in their host galaxies.Environmental Imprints of Dark Matter and Accretion Disks on Eccentric EMRIs around Kerr Black Holes
Extreme-mass-ratio inspirals (EMRIs), systems in which a stellar-mass compact object spirals into a supermassive black hole ($M_1$), are prime targets for the space-based gravitational-wave…
