Discovery of two new millisecond pulsars towards the Galactic bulge

J. Berteaud, F. Calore, M. Clavel +13

The mysterious Galactic Center Excess of gamma rays could be explained by a large population of millisecond pulsars hiding in the Galactic bulge, too faint to be detected as indivi…

Revealing the accelerating wind in the inner region of the colliding-wind binary WR 112

John D. Monnier, Yinuo Han, Michael F. Corcoran +17

Colliding winds in massive binaries generate X-ray-bright shocks, synchrotron radio emission, and sometimes even dusty "pinwheel" spirals. We report the first X-ray detections of t…

Characterization of type Ibn SNe

D. Farias, C. Gall, V. A. Villar +29

Type Ibn supernovae (SNe) are characterized by narrow helium (He I) lines from photons produced by the unshocked circumstellar material (CSM). About 80 SNe Ibn have been discovered…

Frequency evolution of pulsar emission: Further evidence for fan beam model

P. Jaroenjittichai, S. Johnston, S. Dai +7

Aims. We explore frequency-dependent changes in pulsar radio emission by analyzing their profile widths and emission heights, assessing whether the simple radius-to-frequency mappi…

Further evidence for natal kick segregation by spectral type in high-mass X-ray binaries

Pornisara Nuchvanichakul, Poshak Gandhi, Christian Knigge +4

High-mass X-ray binaries (HMXBs) are systems in which a neutron star or black hole accretes material from a massive companion. HMXBs are expected to have experienced a supernova in…

Discovery and Analysis of Afterglows from Poorly Localised GRBs with the Gravitational-wave Optical Transient Observer (GOTO) All-sky Survey

Amit Kumar, B. P. Gompertz, B. Schneider +86

Gamma-ray bursts (GRBs), particularly those detected by wide-field instruments such as the Fermi/GBM, pose a challenge for optical follow-up due to their large initial localisation…

Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory

K. Abe, S. Abe, J. Abhir +491

The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…

Near-Infrared Spectroscopy and Detection of Carbon Monoxide in the Type II Supernova SN 2023ixf

Seong Hyun Park, Jeonghee Rho, Sung-Chul Yoon +33

Core-collapse supernovae (CCSNe) may contribute a significant amount of dust in the early universe. Freshly formed coolant molecules (e.g., CO) and warm dust can be found in CCSNe…

GRB 241105A: A test case for GRB classification and rapid r-process nucleosynthesis channels

Dimple, B. P. Gompertz, A. J. Levan +85

Gamma-ray bursts (GRBs) offer a powerful window to probe the progenitor systems responsible for the formation of heavy elements through the rapid neutron capture (r-) process, than…

SN 2024bfu, SN 2025qe, and the early light curves of type Iax supernovae

M. R. Magee, T. L. Killestein, M. Pursiainen +39

Type Iax supernovae (SNe Iax) are one of the most common subclasses of thermonuclear supernova and yet their sample size, particularly those observed shortly after explosion, remai…
