arXiv:2509.07065v1 Announce Type: new Abstract: Recent imaging of supermassive black holes by the Event Horizon Telescope (EHT) has relied on exhaustive parameter-space searches, matching observation...
arXiv:2509.07064v1 Announce Type: new Abstract: The James Webb Space Telescope (\textit{JWST}) opened a new observational window on the primordial Universe. Here we present new JWST NIRSpec integral ...
arXiv:2509.07088v1 Announce Type: new Abstract: The Alfv\'en surface -- where the solar wind exceeds the local Alfv\'en speed as it expands into interplanetary space -- is now routinely probed by NAS...
arXiv:2509.07080v1 Announce Type: new Abstract: Supernovae that interact with hydrogen-poor, helium-rich circumstellar material (CSM), known as Type Ibn supernovae (SNe Ibn), present a unique opportu...
arXiv:2509.07091v1 Announce Type: new Abstract: We present a comprehensive spectroscopic and kinematic analysis of the very metal-poor ([Fe/H] = -2.60 $\pm$ 0.20 dex) giant star HE2159-0551. By inves...
arXiv:2509.07081v1 Announce Type: new Abstract: Following a binary neutron star (BNS) merger, the transient remnant is often a fast-spinning, differentially rotating, magnetised hypermassive neutron ...
arXiv:2509.07083v1 Announce Type: new Abstract: We analyze an ensemble of simulated prestellar cores to facilitate interpretation of structure, kinematics, and lifetime of observed cores. While our t...
Toward the fabric of the Milky Way I. The density of disk streams from a local $250^3$ pc$^3$ volume
arXiv:2509.07075v1 Announce Type: new Abstract: We studied 12 disk streams found in a 250$^3$ pc$^3$ volume in the solar neighborhood, which we define as coeval and comoving stellar structures with a...
arXiv:2509.07074v1 Announce Type: new Abstract: Recent findings from several Pulsar Timing Array (PTA) collaborations point to the existence of a Gravitational Wave Background (GWB) at nanohertz freq...
arXiv:2509.07067v1 Announce Type: new Abstract: Dense young star clusters (YSCs) are ideal environments for dynamical interactions between stars and stellar mass black holes (BHs). In such dense envi...
