Cosmology (11 new)

• Researchers have used DESI DR1 and ACT DR6 data to measure the thermal Sunyaev-Zel'dovich (tSZ) effect from galaxy groups and clusters, providing a new method to infer optical depths. This work is crucial for understanding the early universe and the formation of large-scale structures. (2609.08939)
• Gravitational-wave observations can reveal the existence and properties of primordial black holes (PBHs) that formed in the early universe. The analysis of a potential primordial gravitational-wave background from NANOGrav data suggests that PBHs with masses in the range 4-90 mg are already being probed, opening a new window into the early universe. (2609.11891)
• A study using Hyper Suprime-Cam Year 1 data has demonstrated the potential of LSST-DESC analysis pipelines for cosmological inference. The analysis of cosmic shear, galaxy clustering, and galaxy-galaxy lensing jointly constrains cosmological parameters, providing a foundation for future LSST cosmological analyses. (2610.12552)

Galaxies (18 new)

• A new method using multi-tracer kinematic decomposition has been applied to JWST observations of the Seyfert galaxy NGC 5728, revealing a star-forming ring and an AGN-driven biconical outflow. This technique provides a general and scalable approach for separating complex emission components in IFS data. (2609.30232)

High-energy astrophysics (11 new)

• A new radio continuum study of the Large Magellanic Cloud supernova remnant N 132D reveals a close connection between thermal and non-thermal plasma components, complex magnetic field structures, and a constant partition between electron and magnetic field energy densities. These findings provide new insights into particle acceleration and shock evolution in young supernova remnants. (2610.11606)
• The nature of magnetic turbulence in Tycho's SNR is investigated using X-ray observations, showing a shorter turbulence length scale than previous radio observations. This suggests a more complex magnetic field structure and is crucial for understanding cosmic ray acceleration processes. (2610.11832)
• The ASKAP monitoring program of the Rubin Deep Drilling Fields provides serendipitous radio observations and real-time data dissemination, contributing to the understanding of transient phenomena like tidal disruption events and extreme scattering events. This lays the groundwork for integrating future radio imaging surveys into multi-messenger alert streams. (2610.13011)

Solar and stellar (4 new)

• A weakly magnetic candidate star, xi Persei, exhibits a rotation period of 2.040514 days, as observed in its NIV 1718 Å line. This periodicity suggests the presence of a weak global surface magnetic field, influencing the star's wind and possibly creating a magnetospheric disc. This finding could provide insights into the magnetic field dynamics of massive stars. (2610.12323)
• 3D RMHD simulations reveal the formation of a spicule-like event in a solar magnetic field. The event involves magnetic reconnection and the generation of Alfvén waves, contributing to energy and mass transport in the solar atmosphere. This study enhances our understanding of solar dynamics and the mechanisms driving mass and energy outflows from the Sun. (2610.13173)

Planets and the Solar System (18 new)

• This paper introduces a new method for simulating the thermodynamics of protoplanetary disks, incorporating gas, radiation, and multiple dust species. This approach aims to more accurately model the complex interactions within these disks, which are crucial for understanding planet formation. (2609.30252)
• The study revises the masses of three transiting planets around the young K2-233 star, finding significant variations depending on the activity-modelling strategy used. The results suggest that atmospheric mass loss is a significant factor in the evolution of these planets, potentially leading to different final states such as a low-mass sub-Neptune or a super-Earth. (2610.09954)
• This research challenges the existence of 'Mega-Earths'—rocky planets with masses above the typical upper limit for rocky planets—by suggesting that their apparent characteristics are artifacts of stellar activity. The study questions the reliability of certain methods for estimating the masses of rocky planets around active stars. (2610.12600)

Instruments and methods (4 new)

• The Einstein Probe's Follow-up X-ray Telescope (FXT) has been calibrated using pulsars observed in different readout modes. The timing system of FXTA and FXTB is consistent across modes and aligns well with NICER results. The Crab pulsar's TOAs show a systematic advance, and the absolute timing accuracy is estimated to be 6 μs for FXTA and 31 μs for FXTB in timing mode. (2610.12943)
• The Habitable Worlds Observatory (HWO) is considering an ultraviolet (UV) instrument with multiple modes, including a multi-object spectrograph, far ultraviolet imager, high-resolution spectrograph, and integral-field spectrograph. This paper outlines the basic design and potential capabilities of the UV instrument, which will be crucial for future scientific investigations. (2610.12974)
