Dissecting the Nuclear Structure of NGC 5548 with XRISM. I. Physical Properties of the Highly Ionized Outflows
Missagh Mehdipour, Jon M. Miller, Jelle S. Kaastra +21
We present a detailed spectral analysis of an X-Ray Imaging and Spectroscopy Mission (XRISM) observation of the prototypical Seyfert 1 galaxy NGC 5548. XRISM's Resolve microcalorim…
Time-resolved XRISM spectroscopy reveals the evolution and structure of the corona in MCG-6-30-15
D. R. Wilkins, L. W. Brenneman, A. Ogorzalek +7
We present a time-resolved analysis of high-resolution spectra of the AGN MCG-6-30-15 obtained by XRISM alongside broadband spectra from NuSTAR and XMM-Newton during a coordinated…
The dynamic central environment of NGC 3516 revealed by XRISM
Anna Juráňová, Erin Kara, Ehud Behar +15
We present a detailed, time-resolved analysis of the Fe K band of the Seyfert 1.5 galaxy NGC 3516 observed with XRISM. The 249 ks observation spanning 310 ks in elapsed time…
A Sharper View of the X-ray Spectrum of MCG--6-30-15 with XRISM, XMM-Newton and NuSTAR
Laura W. Brenneman, Daniel R. Wilkins, Anna Ogorzałek +15
We present a time-averaged spectral analysis of the 2024 XRISM observation of the narrow-line Seyfert-1 galaxy MCG--6-30-15, taken contemporaneously with XMM-Newton and NuSTAR. Our…
Time-dependent photoionization spectroscopy of the Seyfert galaxy NGC 3783
Liyi Gu, Jelle Kaastra, Daniele Rogantini +4
We present an investigation into the spectroscopic properties of non-equilibrium photoionization processes operating in a time-evolving mode. Through a quantitative comparison betw…
TPHO: a time-dependent photoionisation model for AGN outflows
Daniele Rogantini, Missagh Mehdipour, Jelle Kaastra +3
Outflows in active galactic nuclei (AGN) are considered a promising candidate for driving AGN feedback at large scales. However, without information on the density of these outflow…
Cooling in the X-ray halo of the rotating, massive early-type galaxy NGC 7049
A. Juráňová, N. Werner, M. Gaspari +9
The relative importance of the physical processes shaping the thermodynamics of the hot gas permeating rotating, massive early-type galaxies is expected to be different from that i…
The SERMON project: 48 new field Blazhko stars and an investigation of modulation-period distribution
Marek Skarka, Jiří Liška, Reinhold F. Auer +3
We investigated 1234 fundamental mode RR Lyrae stars observed by the All Sky Automated Survey (ASAS) to identify the Blazhko (BL) effect. A sample of 1547 BL stars from the literat…
Possible candidates for multiple occurrence of variable stars in the VSX catalogue
Jiri Liska, Marek Skarka, Reinhold Friedrich Auer +2
A paper about variable stars with possible multiple occurrence in the VSX catalogue is presented. Our main criteria for identification of such duplicities were the angular distance…
