A Fast, Hot Wind from a Nuclear Starburst
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +137
Galaxies with intense star formation often host multiphase, galaxy-scale winds powered by supernovae and fast stellar winds. These are strong enough to disrupt the star-forming int…
A XRISM/Resolve view of the dynamics in the hot gaseous atmosphere of M87
XRISM Collaboration, M. Audard, H. Awaki +138
The XRISM/Resolve microcalorimeter directly measured the gas velocities in the core of the Virgo Cluster, the closest example of AGN feedback in a cluster. This proximity allows us…
Chlorine and Potassium Enrichment in the Cassiopeia A Supernova Remnant
XRISM collaboration
The elements in the universe are synthesized primarily in stars and supernovae, where nuclear fusion favors the production of even-Z elements. In contrast, odd-Z elements are less…
XRISM constraints on unidentified X-ray emission lines, including the 3.5 keV line, in the stacked spectrum of ten galaxy clusters
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +150
We stack 3.75 Megaseconds of early XRISM Resolve observations of ten galaxy clusters to search for unidentified spectral lines in the 2.5-15 keV band (rest frame), including t…
Stratified wind from a super-Eddington X-ray binary is slower than expected
XRISM collaboration, Marc Audard, Hisamitsu Awaki +132
Accretion discs in strong gravity ubiquitously produce winds, seen as blueshifted absorption lines in the X-ray band of both stellar mass X-ray binaries (black holes and neutron st…
Structured ionized winds shooting out from a quasar at relativistic speeds
XRISM collaboration
Evidence indicates that supermassive black holes exist at the centers of most galaxies. Their mass correlates with the galactic bulge mass, suggesting a co-evolution with their hos…
Evidence for Charge Exchange Emission in Supernova Remnant N132D from XRISM/Resolve Observations
Liyi Gu, Hiroya Yamaguchi, Adam Foster +24
XRISM has delivered one of its first light observations on N132D, the X-ray brightest supernova remnant in the Large Magellanic Cloud. Utilizing 193 ks of high-resolution X-ray spe…
The bulk motion of gas in the core of the Centaurus galaxy cluster
XRISM collaboration
Galaxy clusters, the largest gravitationally bound structures in the Universe, contain vast amounts of dark matter, galaxies, and hot ionised gas known as the intracluster medium (…
Overionized plasma in the supernova remnant Sagittarius A East anchored by XRISM observations
XRISM Collaboration
Sagittarius A East is a supernova remnant with a unique surrounding environment, as it is located in the immediate vicinity of the supermassive black hole at the Galactic center, S…
Unveiling the Cosmic Chemistry II: "Direct" -based metallicity of galaxies at 3 10 with JWST/NIRSpec
Priyanka Chakraborty, Arnab Sarkar, Randall Smith +10
We report the detection of the [O III] auroral line in 42 galaxies within the redshift range of . These galaxies were selected from publicly available JWST data release…
The XRISM/Resolve view of the Fe K region of Cyg X-3
XRISM Collaboration
The X-ray binary system Cygnus X-3 (4U 2030+40, V1521 Cyg) is luminous but enigmatic owing to the high intervening absorption. High-resolution X-ray spectroscopy uniquely probes th…
Detection of new galaxy candidates at z > 11 in the JADES field using JWST NIRCam
Priyanka Chakraborty, Arnab Sarkar, Scott Wolk +5
We report the detection of six new galaxy candidates with photometric redshifts 11 within the JWST Advanced Deep Extragalactic Survey (JADES) GOODS-S and GOODS-N fields. Th…
The Mira Distance to M101 and a 4% Measurement of H0
Caroline D. Huang, Wenlong Yuan, Adam G. Riess +8
The giant spiral galaxy M101 is host to the nearest recent Type Ia Supernova (SN 2011fe) and thus has been extensively monitored in the near-infrared to study the late-time lightcu…
Flux Contribution and Geometry of the Charge Exchange Emission in the Starburst Galaxy M82
Hiromichi Okon, Randall K. Smith, Adrien picquenot +1
Recent X-ray studies of starburst galaxies have found that Charge eXchange (CX) commonly occurs between the outflowing hot plasma and cold gas, possibly from swept-up clouds. Howev…
Investigating the impact of atomic data uncertainties on measured physical parameters of the Perseus galaxy cluster
Priyanka Chakraborty, Rachel Hemmer, Adam R. Foster +4
Accurate atomic data and plasma models are essential for interpreting the upcoming high-quality spectra from missions like XRISM and Athena. Estimating physical quantities, like te…
New resonance scattering model in AtomDB: application to line suppression in galaxy clusters and elliptical galaxies
Priyanka Chakraborty, Adam Foster, Randall Smith +2
In this paper, we present a simple, one-step, self-consistent, and fast resonance scattering model rsapec based on the AtomDB database. This model can be used as an alternative to…
Galaxy formation with wave/fuzzy dark matter: The core-halo structure and the solitonic imprint
Alvaro Pozo, Razieh Emami, Philip Mocz +9
Dark matter-dominated cores have long been claimed for the well-studied local group dwarf galaxies. More recently, extended stellar halos have been uncovered around several of thes…
