Diverse ionized gas conditions in a dynamically hot, interacting galaxy at revealed by JWST/NIRSpec IFU

Ryota Ikeda, Takahiro Morishita, Massimo Stiavelli +1

We present a spatially and spectrally resolved study of an interacting galaxy, Gz9p3 at , using the James Webb Space Telescope NIRSpec/G395H IFU observation with high-spect…

Interacting stellar winds feeding Sgr A*: from the system of mass-losing stars to the binary IRS 16SW

Diego Calderón, Jorge Cuadra, Christopher M. P. Russell +3

The discovery of cold structures around Sgr A* has challenged our understanding of the gas dynamics and thermodynamic state of the plasma in its vicinity. This work aims to constra…

A comprehensive cluster census of Orion. An application of the Significance Mode Analysis (SigMA) algorithm

Alena Rottensteiner, Sebastian Ratzenböck, João Alves +2

Precise astrometric surveys and modern clustering algorithms are working in step to transform our view of star-forming regions. By revealing a much richer substructure than previou…

A Critical Eddington Ratio for X-Shaped Radio Galaxies

David Garofalo

We derive a quantitative condition for the formation of X-shaped radio galaxies by evaluating the competition between black hole spin evolution and the radiative fading of relic pl…

Identifying AGNs from X-ray detectionsII: Metallicity calibrations for the and diagnostics

Mark Armah, O. L. Dors, Rogério Riffel +4

Emission-line ratios from ions with nearly identical ionization potentials offer a robust solution to the degeneracies inherent to traditional active galactic nuclei (AGNs) metalli…

JWST Whirlpool Galaxy Treasury: Mid-Infrared Emission in M51 and its Relation to Gas Column and Star Formation

Mansi Padave, Karin M. Sandstrom, Daniel A. Dale +25

Using JWST/MIRI imaging of M51 in eight broadband filters, we investigate correlations of mid-infrared emission from polycyclic aromatic hydrocarbons (PAHs) and dust continuum with…
