A Vision for Little Red Dots in the Low-Redshift Universe with ALMA2040
Fengwu Sun, Xiaojing Lin, Miguel Pereira-Santaella +1
The discovery of Little Red Dots (LRDs) at high redshifts with JWST has revealed a previously unknown phase of black-hole growth. However, their black-hole (BH) masses, BH-to-stell…
GATOS: Distinct Feedback Modes in AGN Central Regions Revealed by Spatially Resolved JWST Spectroscopy
Lulu Zhang, Chris Packham, Erin K. S. Hicks +25
This manuscript presents JWST MIRI/MRS observations of the central pc regions of five active galactic nuclei (AGN) spanning a wide range of luminosities (${\rm l…
Kinematic detection of dusty outflows from active galactic nuclei: Polycyclic aromatic hydrocarbon kinematics of type 2 quasars with JWST/MIRI spectroscopy
Fergus R. Donnan, Cristina Ramos Almeida, Omaira González Martín +5
Active galactic nuclei (AGN) are thought to have dusty outflows, but unlike in the gas phase, it is challenging to measure the kinematics of dust. We present the detection and anal…
GATOS XIV: The first direct kinematic evidence of dusty outflows from AGN via PAH kinematics of local Seyfert galaxies with JWST
Fergus R. Donnan, Ismael García-Bernete, Dimitra Rigopoulou +30
We present the first spatially resolved kinematic evidence for dust in the outflows of Active Galactic Nuclei (AGN). We utilise observations from JWST with NIRSpec IFU and MIRI MRS…
Abundant hydrocarbons in a buried galactic nucleus with signs of carbonaceous grain and polycyclic aromatic hydrocarbon processing
I. García-Bernete, M. Pereira-Santaella, E. González-Alfonso +5
Hydrocarbons play a key role in shaping the chemistry of the interstellar medium (ISM), but their enrichment and relationship with carbonaceous grains and polycyclic aromatic hydro…
The Supermassive Black Hole in the Nearby Spiral Galaxy M81: A Robust Mass from JWST/NIRSpec Stellar Dynamics
Dieu D. Nguyen, Tuan N. Le, Michele Cappellari +9
Despite its proximity, the mass of the supermassive black hole (SMBH) in the spiral galaxy M81 (NGC~3031) has remained uncertain, with previous dynamical measurements being unrelia…
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…
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…
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…
Simulating intermediate black hole mass measurements for a sample of galaxies with nuclear star clusters using ELT/HARMONI high spatial resolution integral-field stellar kinematics
Dieu D. Nguyen, Michele Cappellari, Hai N. Ngo +8
Understanding the demographics of intermediate-mass black holes (IMBHs, M) in low-mass galaxies is key to constraining black hole seed format…
Behind the Mask: can HARMONI@ELT detect biosignatures in the reflected light of Proxima b?
Sophia R. Vaughan, Jayne L. Birkby, Niranjan Thatte +7
Proxima b is a rocky exoplanet in the habitable zone of the nearest star system and a key test case in the search for extraterrestrial life. Here, we investigate the characterizati…
On the Viability of Determining Galaxy Properties from Observations I: Star Formation Rates and Kinematics
Kearn Grisdale, Laurence Hogan, Dimitra Rigopoulou +8
We explore how observations relate to the physical properties of the emitting galaxies by post-processing a pair of merging galaxies from the cosmological, hydrodynamical…
HARMONI view of the host galaxies of active galactic nuclei around cosmic noon: Resolved stellar morpho-kinematics and the M- relation
Begoña Garcia-Lorenzo, Ana Monreal-Ibero, Miguel Pereira-Santaella +4
Context. The formation and evolution of galaxies appear linked to the growth of supermassive black holes, as evidenced by empirical scaling relations in nearby galaxies. Understand…
The properties of Polycyclic Aromatic Hydrocarbons in galaxies: constraints on PAH sizes, charge and radiation fields
Dimitra Rigopoulou, Marie Barale, David Clary +7
Based on theoretical spectra computed using Density Functional Theory we study the properties of Polycyclic Aromatic Hydrocarbons (PAH). In particular using bin-average spectra of…
First detection of the 448 GHz ortho-H2O line at high redshift: probing the structure of a starburst nucleus at z = 3.63
C. Yang, E. González-Alfonso, A. Omont +4
Submillimeter rotational lines of H2O are a powerful probe in warm gas regions of the ISM, tracing scales and structures ranging from kpc disks to the most compact and dust-obscure…
