Investigation of Calcium Dust in the Interstellar Medium

Ya-Yu Chu, Sascha Zeegers, Hsien Shang +7

Calcium is a highly depleted element in the interstellar medium (ISM), however its composition in the solid phase remains elusive. The detection of Ca-bearing dust has been limited…

Kinematics of Weak Cool-Core Cluster A3571 Observed with XRISM: Low Cooling Rate Balanced by Low Heating Rate

Hannah McCall, Irina Zhuravleva, Kyoko Matsushita +10

Most XRISM galaxy cluster observations to date have focused on AGN feedback or actively merging systems. The weak cool-core cluster A3571 was observed in four XRISM Cycle 1 pointin…

Silicon, sulfur and iron in the interstellar medium: a high-resolution X-ray spectral study of GX 340+0

Daniele Rogantini, Claude Canizares, Elisa Costantini +5

High-resolution X-ray spectroscopy provides a powerful probe of the interstellar medium (ISM), giving direct access to the composition and physical state of dust grains and atomic…

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…

AGN STORM 2: VIII. Investigating the Narrow Absorption Lines in Mrk 817 Using HST-COS Observations

Maryam Dehghanian, Nahum Arav, Gerard A. Kriss +39

We observed the Seyfert 1 galaxy Mrk817 during an intensive multi-wavelength reverberation mapping campaign for 16 months. Here, we examine the behavior of narrow UV absorption lin…

The outflowing ionised gas of I Zw 1 observed by HST COS

A. Juráňová, E. Costantini, G. A. Kriss +8

We present an analysis of the HST COS spectrum of IZw1 aiming to probe the absorbing medium associated with the active galactic nucleus (AGN). We fitted the emission spectrum and p…
