78 new papers, 12 highlights. Written by qwen2.5:7b.

Cosmology (10 new)

• A new approach to understanding gravitational clustering uses a transition probability of Lagrangian trajectories, offering a fresh perspective on the two-point function and its suppression at large scales. (2609.30251)

Galaxies (21 new)

• Complex organic molecules (COMs) in L1551 IRS 5 arise from both radiative heating and localized accretion shocks, indicating a mix of thermal and shock-induced chemistry in protostellar disks. (2609.07991)
• The gas fundamental metallicity relation (GFMR) in star-forming galaxies at cosmic noon is primarily driven by stellar mass, with molecular gas playing a secondary role. (2609.20921)
• JWST observations of M82 and NGC 253 reveal that PAH features trace different kinematic components, with PAHs more closely associated with ionized gas than molecular gas. (2610.07410)
• The nearby dwarf galaxy KDG 162, at a distance of 3.48 Mpc, is found to be relatively isolated and has a modest recent star formation history. (2610.08905)

High-energy astrophysics (17 new)

• The strongly-lensed superluminous supernova 2025wny at z = 2.0155 shows a magnetar-powered explosion and high-velocity outflows, matching lower-redshift SLSNe. The high Lyα escape fraction suggests significant feedback on the host galaxy. (2610.08903)
• A transient ultraluminous X-ray source (ULX) in M31 was discovered, with a peak luminosity of ~10^39 erg/s. The source's spectral evolution suggests increasing advection during the outburst, and it may be powered by a neutron star with super-Eddington accretion. (2610.08918)
• The Compton Spectrometer and Imager (COSI) is expected to detect ~47-89 short gamma-ray bursts (sGRBs) per year, with ~7-10 localized events. This will provide valuable insights into the population of sGRBs and their progenitors. (2610.08940)

Solar and stellar (14 new)

• AT 2025abao, an asymptotic giant branch (AGB) star that underwent a luminous red nova event, has been shown to have a main-sequence companion inspiralling through its wind. The companion's plunge into the AGB star's envelope and the resulting shock wave provide insights into common envelope evolution, potentially forming a close compact binary system. This study, based on arXiv ID: 2610.05769, fills a significant gap in our understanding of compact binary formation. (2610.05769)

Planets and the Solar System (10 new)

• The hot Neptune WASP-195b has a spin-orbit alignment with its host star, making it one of the few such systems with a measured obliquity. This suggests a history of disk-driven migration. (2609.02888)

Instruments and methods (6 new)

• A new method based on autoencoders is proposed for analyzing multimodal data from the TAIGA experiment, which can effectively reduce noise and extract essential features. This method can be applied to the joint analysis of data from multiple installations, improving the accuracy of cosmic ray physics and gamma-ray astronomy studies. (2610.08985)
• The BOLT array, developed for the Pierre Auger Observatory, will enhance the unique capabilities of the Observatory by providing high-resolution 3D imaging of lightning propagation, which can help in studying Terrestrial Gamma-ray Flashes (TGFs) in coincidence with their parent lightning discharges. This will provide key insights into the mechanisms responsible for the generation and evolution of these high-energy emissions within thunderstorms. (2610.10434)
