The PAH 3.4 micron feature as a tracer of shielding in the Orion Bar and NGC 6240
N. Thatte, D. Rigopoulou, F. R. Donnan +8
We have carried out a detailed analysis of the 3.4 micron spectral feature arising from Polycyclic Aromatic Hydrocarbons (PAH), using JWST archival data. For the first time in an e…
Extending the Frontier of Spatially-Resolved Supermassive Black Hole Mass Measurements to at : Simulations with ELT/MICADO High-Resolution Mass Models and HARMONI Integral-Field Stellar Kinematics
Dieu D. Nguyen, Michele Cappellari, Tinh Q. T. Le +8
Current spatially resolved kinematic measurements of supermassive black hole (SMBH) masses are largely confined to the local Universe (distances Mpc). We investigate…
Shock-driven heating in the circumnuclear star-forming regions of NGC 7582: Insights from JWST NIRSpec and MIRI/MRS spectroscopy
Oscar Veenema, Niranjan Thatte, Dimitra Rigopoulou +24
We present combined JWST NIRSpec and MIRI/MRS integral field spectroscopy data of the nuclear and circumnuclear regions of the highly dust obscured Seyfert 2 galaxy NGC 7582, which…
Measuring the Central Dark Mass in NGC 4258 with JWST/NIRSpec Stellar Kinematics
Dieu D. Nguyen, Hai N. Ngo, Michele Cappellari +8
We present a new stellar dynamical measurement of the supermassive black hole (SMBH) mass in the nearby spiral galaxy NGC 4258, a critical benchmark for extragalactic mass measurem…
JWST reveals cosmic ray dominated chemistry in the local ULIRG IRAS 072510248
G. Speranza, M. Pereira-Santaella, M. Agúndez +7
We analyse the ro-vibrational absorption bands of various molecular cations (HCO, HCNH, and NH) and neutral species (HCN, HNC, and HCN) detected in the \textit{…
Supermassive black hole mass measurement in the spiral galaxy NGC 4736 Using JWST/NIRSpec stellar kinematics
Dieu D. Nguyen, Hai N. Ngo, Tinh Q. T. Le +12
We present accurate mass measurements of the central supermassive black hole (SMBH) in NGC 4736 (M 94).\ We used the ``gold-standard" stellar absorption features (CO band heads) at…
On unveiling Buried Nuclei with JWST: a technique for hunting the most obscured galaxy nuclei from local to high redshift
I. García-Bernete, F. R. Donnan, D. Rigopoulou +12
We analyze JWST NIRSpec+MIRI/MRS observations of the infrared (IR) Polycyclic Aromatic Hydrocarbon (PAH) features in the central regions (0.26'' at 6 micron; 50-440 pc…
