The First Insights into an Ultraluminous X-ray Pulsar with XRISM: Phase-Resolved High-Resolution Spectroscopy of the Fe K-shell Band of M82 X-2
Shogo B. Kobayashi, Peter Kosec, Kazuki Ampuku +18
During the performance verification phase, XRISM observed the M82 galaxy for a net exposure of 207.7 ks, with the ultraluminous X-ray pulsar (ULXP) X-2 included in the field of vie…
Active Galaxy Science with the Line Emission Mapper: The Case for High-Resolution Soft X-ray Spectroscopy
Kimberly A. Weaver, Jenna M. Cann, Ryan W. Pfeifle +11
This white paper discusses the breadth of science related to active galactic nuclei (AGN) and associated phenomena to be enabled by a mission with microcalorimeter energy resolutio…
Hot Gas Outflow Properties of the Starburst Galaxy NGC 4945
Natalia Porraz Barrera, Sebastian Lopez, Laura A. Lopez +5
We analyze 330 ks of {\it Chandra} X-ray imaging and spectra of the nearby, edge-on starburst and Seyfert Type 2 galaxy NGC 4945 to measure the hot gas properties along the galacti…
Neural ODEs as a discovery tool to characterize the structure of the hot galactic wind of M82
Dustin D. Nguyen, Yuan-Sen Ting, Todd A. Thompson +2
Dynamic astrophysical phenomena are predominantly described by differential equations, yet our understanding of these systems is constrained by our incomplete grasp of non-linear p…
Highly-mass-loaded hot galactic winds are unstable to cool filament formation
Dustin D. Nguyen, Todd A. Thompson, Evan E. Schneider +1
When cool clouds are ram-pressure accelerated by a hot supersonic galactic wind, some of the clouds may be shredded by hydrodynamical instabilities and incorporated into the hot fl…
Neural Astrophysical Wind Models
Dustin D. Nguyen
The bulk kinematics and thermodynamics of hot supernovae-driven galactic winds is critically dependent on both the amount of swept up cool clouds and non-spherical collimated flow…
Dynamics of hot galactic winds launched from spherically-stratified starburst cores
Dustin D. Nguyen, Todd A. Thompson, Evan E. Schneider +2
The analytic galactic wind model derived by Chevalier and Clegg in 1985 (CC85) assumes energy and mass-injection within the starburst galaxy nucleus. However, th…
X-ray Properties of NGC 253's Starburst-Driven Outflow
Sebastian Lopez, Laura A. Lopez, Dustin D. Nguyen +5
We analyze image and spectral data from 365~ks of observations from the {\it Chandra} X-ray Observatory of the nearby, edge-on starburst galaxy NGC 253 to constrain proper…
Galactic winds and bubbles from nuclear starburst rings
Dustin D. Nguyen, Todd A. Thompson
Galactic outflows from local starburst galaxies typically exhibit a layered geometry, with cool K flow sheathing a hotter K, cylindrically-collimated, X-ray emittin…
Mass-Loading and Non-Spherical Divergence in Hot Galactic Winds: Implications for X-ray Observations
Dustin D. Nguyen, Todd A. Thompson
Cool clouds are expected to be destroyed and incorporated into hot supernova-driven galactic winds. The mass-loading of a wind by the cool medium modifies the bulk velocity, temper…
Temperature and Metallicity Gradients in the Hot Gas Outflows of M82
Laura A. Lopez, Smita Mathur, Dustin D. Nguyen +2
We utilize deep Chandra X-ray Observatory imaging and spectra of M82, the prototype of a starbursting galaxy with a multiphase wind, to map the hot plasma properties along the mino…
