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 ...
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:2509.07083v1 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...
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...
