Stellar mass loading drives dissipation and reacceleration in AGN jets: Explaining VLBI-Gaia offsets and constraining jet power

G. Fichet de Clairfontaine, M. Perucho, J. M. Martí +1

Recent Very Long Baseline Interferometry (VLBI) and Gaia astrometry reveal systematic milliarcsecond-scale offsets between the radio and optical centroids of active galactic nuclei…

GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow

Ramandeep Gill, Rosa L. Becerra, Antonio de Ugarte Postigo +54

We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt…

Parameter Estimation Horizon of Core-Collapse Supernovae with Current and Next-Generation Gravitational-Wave Detectors

Almat Akhmetali, Y. Sultan Abylkairov, Daniil Orel +7

Core-collapse supernovae (CCSNe) are powerful sources of gravitational waves (GWs). These signals propagate essentially unobstructed, providing a unique probe of the supernova cent…

Toward More Realistic Machine-Learning Inference of the Dense-Matter Equation of State from Supernova Gravitational Waves

Almat Akhmetali, Y. Sultan Abylkairov, Marat Zaidyn +6

Gravitational waves from core-collapse supernovae offer a unique probe of the equation of state (EOS) of dense nuclear matter. For rapidly rotating stars, previous machine-learning…

Evidence of a non-equipartition energy regime in 1803+784 Core-shift and Faraday rotation measurements from simultaneous multi-frequency polarimetric VGOS observations

V. Pérez-Díez, I. Martí-Vidal, E. Albentosa-Ruiz +1

Context. Compact jets from active galactic nuclei (AGN) are commonly assumed to be in equipartition between particle and magnetic-field energy densities at the regions where the ra…

3D insights into SN 1987A: ALMA observations compared to hydrodynamical explosion simulations

R. Wesson, M. Gabler, M. Lyons +9

We obtain three-dimensional distributions of CO and SiO molecules from high spatial resolution (0.03--0.06") ALMA observations of SN 1987A at two different epochs. The evolution be…

Locating the missing large-scale emission in the jet of M87* with short EHT baselines

Boris Georgiev, Paul Tiede, Sebastiano D. von Fellenberg +280

In Very-Long Baseline Interferometric arrays, nearly co-located stations probe the largest scales and typically cannot resolve the observed source. In the absence of large-scale st…

Neutrino flavor instabilities in neutron star mergers with moment transport: Slow, fast, and collisional modes

Julien Froustey, Francois Foucart, Christian Hall +5

Determining where, when, and how neutrino flavor oscillations must be included in large-scale simulations of hot and dense astrophysical environments is an enduring challenge that…
