JWST Observations of Starbursts: The motion of dust - PAH kinematics of M82 and NGC 253 with JWST/MIRI spectroscopy
Fergus R. Donnan, Karin Sandstrom, Alberto D. Bolatto +27
We present an analysis of dust kinematics in the local starburst galaxies M82 (NGC 3034) and NGC 253 using Polycyclic Aromatic Hydrocarbon (PAH) features observed with JWST/MIRI sp…
Ages of the resolved stellar populations inside the JWST/MIRI bubbles in NGC 628
Avinash Ck, Divakara Mayya, Alessandro Bressan +3
JWST images in the MIRI filters are characterized by prominent interstellar bubbles, most of which are expected to be created by mechanical energy injected into the interstellar me…
Bulgeless Evolution And the Rise of Discs (BEARD) I. Physical drivers of the mass-size relation for Milky Way-like galaxies
C. Marrero-de la Rosa, J. Méndez-Abreu, A. de Lorenzo-Cáceres +20
In the standard cold dark matter (CDM) cosmology, the existence of massive pure-disc galaxies remains challenging within the hierarchical framework and is key to understandi…
Bulgeless Evolution And the Rise of Discs (BEARD) III. A numerical simulation view of satellites around Milky-Way analogues
Salvador Cardona-Barrero, Jairo Méndez-Abreu, Adriana de Lorenzo-Cáceres +17
. The existence of massive disc galaxies with little or no bulge challenges conventional cold dark matter model, which typically favours dynamically hot central structure…
Bulgeless Evolution And the Rise of Discs (BEARD) II. The role of mergers in shaping the Milky Way analogues in TNG50
Yetli Rosas-Guevara, Jairo Méndez-Abreu, Adriana de Lorenzo-Cáceres +20
We study the formation and evolution of bulgeless galaxies within the Milky Way-Andromeda analogue sample of the TNG50 simulation. Through kinematic decomposition with Mordor, we i…
Multi-phase AGN-driven outflow in the NLSy1 IRAS 17020+4544. Unveiling dual-feedback and an energy-conserving ionized outflow with MEGARA/GTC integral field spectroscopy
E. Bellocchi, A. L. Longinotti, Q. Salomé +9
The narrow-line Seyfert 1 (NLSy1) galaxy IRAS~17020+4544 is one of the few known sources exhibiting a multi-phase outflow detected in both highly ionized and molecular gas, consist…
Peculiar galaxies I: A Catalog of Polar-Ring Galaxies from the TNG50 Simulation
Josué G. López-Castillo, Manuel Zamora-Avilés, Gilberto C. Gómez +2
The hydrodynamic cosmological simulation, TNG50, is employed to conduct an analysis of multi-spin galaxies that exhibit ringed structures composed of gas and stars that orbit nearl…
Spatially-resolved TRGB JWST color-magnitude as a tool to measure fossil stellar metallicity gradients in disk galaxies: NGC 628
Avinash CK, Y. Divakara Mayya, Alessandro Bressan +1
We use archival JWST/NIRCam images in the F115W, F150W, and F200W filters to measure the Tip of the Red Giant Branch (TRGB) magnitudes across the disk of the late-type spiral galax…
JWST Observations of Starbursts: Massive Star Clusters in the Central Starburst of M82
Rebecca C. Levy, Alberto D. Bolatto, Divakara Mayya +25
We present a near infrared (NIR) candidate star cluster catalog for the central kiloparsec of M82 based on new JWST NIRCam images. We identify star cluster candidates using the F25…
JWST Observations of Starbursts: Cold Clouds and Plumes Launching in the M82 Outflow
Deanne B. Fisher, Alberto D. Bolatto, John Chisholm +28
In this paper we study the filamentary substructure of 3.3 m PAH emission from JWST/NIRCam observations in the base of the M82 star-burst driven wind. We identify plume-like sub…
JWST Observations of Starbursts: Polycyclic Aromatic Hydrocarbon Emission at the Base of the M 82 Galactic Wind
Alberto D. Bolatto, Rebecca C. Levy, Elizabeth Tarantino +37
We present new observations of the central 1 kpc of the M 82 starburst obtained with the James Webb Space Telescope (JWST) near-infrared camera (NIRCam) instrument at a resolution…
The cluster initial mass function of the M82 disk Super Star Clusters
Bolivia Cuevas-Otahola, Divakara Mayya, Jesus Arriaga-Hernandez +2
The presence of a population of a large number (400) of almost coeval (100--300 Myr) super star clusters (SSCs) in the disk of M82 offers an opportunity to construct the Clus…
