A Brush with Turbulence: Probing the ICM Dynamics in the Merging Toothbrush Cluster using XRISM
Anjali Madangarli, Aurora Simionescu, Huub Röttgering +11
The Toothbrush Cluster (1RXS J0603.3+4214) is known for its northern radio relic, radio halo, and highly disturbed X-ray morphology. It shows features of both shock-driven and turb…
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…
Fanaroff-Riley dichotomy of radio galaxies and the Malmquist bias
Ashok K. Singal, Kamlesh Rajpurohit
We examine the possibility that a claimed dependence of the FR 1/2 break value in radio luminosity on the absolute magnitude of the optical host galaxy could be due to the Malmquis…
Dependence of Fanaroff--Riley break of radio galaxies on luminosity and redshift
Ashok K. Singal, Kamlesh Rajpurohit
We investigate the dependence of the Fanaroff-Riley (FR) 1/2 dichotomy of radio galaxies on their luminosities and redshifts. Because of a very strong redshift-luminosity correlati…
