Abstract We present new observations of the central 1 kpc M82 starburst obtained with James Webb Space Telescope near-infrared camera instrument at a resolution θ ∼ 0.″05–0.″1 (∼1–2 pc). The data comprises images in three mostly continuum filters (F140M, F250M, and F360M), that contain [Fe ii ] (F164N), H 2 v = → 0 (F212N), 3.3 μ m polycyclic aromatic hydrocarbon (PAH) feature (F335M). find prominent plumes PAH emission extending outward from region, together network complex filamentary...
Abstract We present a 12 CO( J = 2−1) survey of 60 local galaxies using data from the Atacama Compact Array as part Extragalactic Database for Galaxy Evolution: ACA EDGE survey. These all have integral field spectroscopy CALIFA Compared to other galaxy surveys, is designed mitigate selection effects based on CO brightness and morphological type. Of in EDGE, 36 are star formation main sequence, 13 red 11 lie “green valley” transition between these sequences. test how quenching processes...
We present a study of new 7.7-11.3 $\mu$m data obtained with the James Webb Space Telescope Mid-InfraRed Instrument in starburst galaxy M 82. In particular, we focus on dependency integrated CO(1-0) line intensity MIRI-F770W and MIRI-F1130W filter intensities to investigate correlation between CO content 7.7 11.3 features from polycyclic aromatic hydrocarbons (PAH) 82's outflows. To perform our analysis, identify clouds using archival $^{12}$CO($J$=1-0) NOEMA moment 0 map within 2 kpc center...

Abstract In this paper we study the filamentary substructure of 3.3 $\mu$m PAH emission from JWST/NIRCam observations in base M 82 star-burst driven wind. We identify plume-like within with widths ∼50 pc. Several those plumes extend to edge field-of-view, and thus are at least 200–300 pc length. region outflow, vast majority (∼70 per cent) is associated plumes. show that structures contain smaller scale ‘clouds’ ∼5–15 pc, they morphologically similar results ‘cloud-crushing’ simulations....
Magnetic fields (B fields) have an impact on galaxy evolution multiple scales. They are particularly important for starburst galaxies, where they play a crucial role in shaping the interstellar medium (ISM), influencing star formation processes and interacting with galactic outflows. The primary aim of this study is to obtain parsec-scale map dust polarisation B field structure within central region NGC253. This includes examining relationship between morphology fields, outflows, spatial...
Abstract We present a near-infrared (NIR) candidate star cluster catalog for the central kiloparsec of M82 based on new JWST NIRCam images. identify candidates using F250M filter, finding 1357 with stellar masses >10 4 M ⊙ .

Abstract We characterize the local (2 kpc sized) environments of Type Ia, II, and Ib/c supernovae (SNe) that have recently occurred in nearby ( d ≲ 50 Mpc) galaxies. Using ultraviolet (UV; from Galaxy Evolution Explorer) infrared (IR; Wide-field Infrared Survey maps 359 galaxies a sample 472 SNe, we measure star formation rate surface density (Σ SFR ) stellar mass ⋆ 2 beam centered on each SN site. show core-collapse SNe are preferentially located along resolved galactic star-forming main...
We present new observations of the central 1 kpc M 82 starburst obtained with James Webb Space Telescope (JWST) near-infrared camera (NIRCam) instrument at a resolution ~0.05"-0.1" (~1-2 pc). The data comprises images in three mostly continuum filters (F140M, F250M, and F360M), that contain [FeII] (F164N), H2 v=1-0 (F212N), 3.3 um PAH feature (F335M). find prominent plumes emission extending outward from region, together network complex filamentary substructure edge-brightened bubble-like...
