Probing jet base emission of M87* with the 2021 Event Horizon Telescope observations

Saurabh, Hendrik Müller, Sebastiano D. von Fellenberg +282

We investigate the presence and spatial characteristics of the jet base emission in M87* at 230 GHz, enabled by the enhanced uv coverage in the 2021 Event Horizon Telescope (EHT) o…

Radio properties of the quasi-periodic eruption source RXJ1301.9+2747 at parsec scales

S. D. von Fellenberg, R. Arcodia, P. Benke +6

Quasi-periodic eruptions (QPEs) are repeating soft X-ray flares associated with galactic nuclei. Several recent works have found evidence that the accretion flow in the galactic nu…

Aql X-1 from dawn 'til dusk: the early rise, fast state transition and decay of its 2024 outburst

A. Marino, F. Coti Zelati, K. Alabarta +36

Transient Low-Mass X-ray Binaries (LMXBs) are usually first detected by all-sky X-ray monitors when they enter new outbursts, typically at X-ray luminosities above 10…

Horizon-scale variability of M87* from 2017--2021 EHT observations

The Event Horizon Telescope Collaboration

We report three epochs of polarized images of M87* at 230\,GHz using data from the Event Horizon Telescope (EHT) taken in 2017, 2018, and 2021. The baseline coverage of the 2021 ob…

Dense Matter in Neutron Stars with eXTP

Ang Li, Anna L. Watts, Guobao Zhang +82

In this White Paper, we present the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission to constrain the equation of state of dense matter in neutron stars, explo…

Suppression of composition -modes in chemically-equilibrating warm neutron stars

Tianqi Zhao, Peter B. Rau, Alexander Haber +3

We investigate the impact of chemical equilibration and the resulting bulk viscosity on non-radial oscillation modes of warm neutron stars at temperatures up to MeV, r…
