Cosmology (14 new)

• The second data release of the Dark Energy Spectroscopic Instrument (DESI) prefers a dark energy component whose equation of state is dynamical, favoring a phantom crossing at a redshift of 0.4. The local limit of nonlocal gravity, a teleparallel extension of general relativity, offers a natural explanation for this behavior. The model constructs a susceptibility function that reproduces the CPL behavior favored by DESI data, showing a characteristic low-redshift dip with depth β = -0.025 ± 0.007 at z 0.4. (2609.26517)

Galaxies (25 new)

• A study of the hierarchical structure of filaments in molecular clouds reveals a sub-linear length-mass relation close to L M0.5, consistent across multiple resolutions and hierarchical decompositions. This finding helps understand the formation and evolution of star-forming regions. (2609.19369)
• Observations of high-redshift galaxies with enhanced N/O ratios suggest that strong winds from rotating massive stars during the Wolf-Rayet phase can explain these enhancements. This supports the idea that such winds are crucial for metal enrichment in the early universe. (2609.26998)
• A new detection of thermal radio recombination line emission from the high-mass protostar IRAS18162-2048 provides insights into the physical conditions in the innermost regions of massive star-forming regions, which are otherwise difficult to observe. (2610.03343)
• A study of dual active galactic nuclei (AGN) in galaxy groups at cosmic noon finds that both AGN have similar black hole masses and luminosities, indicating that they are likely part of the same merger remnant. This provides new insights into the growth and accretion processes of AGN in merging galaxies. (2610.10683)

High-energy astrophysics (30 new)

• Recent AMS-02 data on the energy spectra of cosmic rays, including lithium, beryllium, boron, carbon, nitrogen, and oxygen, show that these elements exhibit solar modulation parameters consistent with protons and helium within a modified force-field approximation framework. This suggests a unified model for the solar modulation of cosmic rays across different elements. (2609.13633)
• A study using physics-informed neural networks (PINNs) and data-driven models reconstructs the X-ray light curves of gamma-ray bursts, reducing the uncertainty in key parameters like the plateau end time, plateau flux, and post-plateau decay index. This improves the cosmological statistical power of GRBs. (2609.15261)
• An evolutionary study of neutron star low-mass X-ray binaries (LMXBs) suggests that the transient accretion behavior of LMXBs is primarily driven by the thermal-viscous instability in the accretion disk. The study provides a broader perspective on the transient and persistent phases of LMXBs, enhancing our understanding of accretion-ejection processes. (2609.21324)
• A new model of the Fermi bubbles in the Milky Way suggests that the gamma-ray halo-like emission is beyond known astrophysical emissions, indicating a possible new source or process in the Galactic halo. This model uses a large set of alternative galactic diffuse emission models and different fitting schemes to assess the impact of increased modeling complexity. (2610.10728)

Solar and stellar (16 new)

• Observations of solar plage using the Daniel K. Inouye Solar Telescope reveal significant magnetic oscillations, consistent with slow magnetoacoustic waves. These findings help understand the dynamics of the low chromosphere and could contribute to models of solar heating. (2609.08089)

Planets and the Solar System (9 new)

• The study presents the performance of a new integrator, Lobbie, which demonstrates excellent long-term stability and computational efficiency in simulating the Solar System. Lobbie outperforms traditional methods in terms of energy conservation and computational speed, making it a powerful tool for long-term dynamical simulations. (2609.10809)
• Two new low-mass-ratio planetary microlensing events, KMT-2021-BLG-0247 and MOA-2023-BLG-169, are reported. KMT-2021-BLG-0247 offers unusually tight constraints on the physical properties of the lens system, while MOA-2023-BLG-169, due to its extremely faint source, presents a broad family of strongly correlated solutions, highlighting the challenges and potential of high-magnification events. (2610.10308)

Instruments and methods (8 new)

• This work characterizes silicon nitride (SiNx) films deposited at low temperatures for use in superconducting detector fabrication. The researchers find that reducing the N2/SiH4 precursor ratio and applying an RF substrate bias during deposition can significantly reduce dielectric loss, which is crucial for improving the efficiency of superconducting circuits. (2610.10767)
• The DeepDISC framework, a scene-level deep-learning approach, is applied to real LSST data, achieving significant improvements in source recovery and classification. The model, fine-tuned on real data, shows a substantial increase in completeness for both galaxies and stars, making it a valuable tool for large-scale surveys. (2610.10986)
