Direct imaging of sub-parsec binary SMBHs in the central galaxy of the NGC 5044 group
Francesco Ubertosi, Gerrit Schellenberger, Ewan O'Sullivan +7
Binary active galactic nuclei (AGN) consist of two supermassive black holes (SMBHs) hosted in a single galaxy that are simultaneously accreting gas. These systems are key to unders…
PSZ2 G181.06+48.47 III: weak-lensing analysis and merging scenario reconstruction of a low-mass cluster with exceptionally-distant radio relics
Eunmo Ahn, Hyejeon Cho, M. James Jee +7
The galaxy cluster PSZ2 G181.06+48.47 () is a post-merging system that exhibits symmetric double radio relics separated by ~2.7 Mpc. We present the first weak-lensing anal…
Spectral analysis of spatially-resolved 3C295 (sub-arcsecond resolution) with the International LOFAR Telescope
Etienne Bonnassieux, Frits Sweijen, Marisa Brienza +11
3C295 is a bright, compact steep spectrum source with a well-studied integrated radio spectral energy distribution (SED) from 132 MHz to 15 GHz. However, spatially resolved spectra…
Exploring the stellar properties of M dwarfs with high-resolution spectroscopy from the optical to the near-infrared
A. S. Rajpurohit, F. Allard, S. Rajpurohit +4
Context. Being the most numerous and oldest stars in the galaxy, M dwarfs are objects of great interest for exoplanet searches. The presence of molecules in their atmosphere compli…
