WISDOM Project -- XXVIII. Molecular gas measurement of the supermassive black hole mass of the galaxy NGC 1387

Pandora Dominiak, Martin Bureau, Fu-Heng Liang +6

Supermassive black hole (SMBH) masses can be measured using molecular gas kinematics. Here we present high angular resolution ( arcsec or pc) Atacama Large Millim…

WISDOM Project - XXVII. Giant molecular clouds of the lenticular galaxy NGC 1387: similarities with spiral galaxy clouds

Fu-Heng Liang, Martin Bureau, Lijie Liu +10

Molecular gas is crucial to understanding star formation and galaxy evolution, but the giant molecular clouds (GMCs) of early-type galaxies (ETGs) have rarely been studied. Here, w…

Stellar-mass black holes on the millimetre fundamental plane of black hole accretion

Jacob S. Elford, Ilaria Ruffa, Timothy A. Davis +5

Recent work revealed the existence of a galaxy "millimetre fundamental plane of black hole accretion", a tight correlation between nuclear mm luminosity, intrinsic - keV…

Neural Deprojection of Galaxy Stellar Mass Profiles

M. J. Yantovski-Barth, Hengyue Zhang, Nolan Smyth +4

We introduce a neural approach to dynamical modeling of galaxies that replaces traditional imaging-based deprojections with a differentiable mapping. Specifically, we train a neura…

WISDOM Project -- XXV. Improving the CO-dynamical supermassive black hole mass measurement in the galaxy NGC 1574 using high spatial resolution ALMA observations

Hengyue Zhang, Martin Bureau, Ilaria Ruffa +5

We present a molecular gas dynamical supermassive black hole (SMBH) mass measurement in the nearby barred lenticular galaxy NGC 1574, using Atacama Large Millimeter/sub-millimeter…

WISDOM project -- XXIII. Star-formation efficiencies of eight early-type galaxies and bulges observed with SITELLE and ALMA

Anan Lu, Daryl Haggard, Martin Bureau +18

Early-type galaxies (ETGs) are known to harbour dense spheroids of stars with scarce star formation (SF). Approximately a quarter of these galaxies have rich molecular gas reservoi…

WISDOM Project -- XXII. A 5% precision CO-dynamical supermassive black hole mass measurement in the galaxy NGC 383

Hengyue Zhang, Martin Bureau, Ilaria Ruffa +8

We present a measurement of the supermassive black hole (SMBH) mass of the nearby lenticular galaxy NGC 383, based on Atacama Large Millimeter/sub-millimeter Array (ALMA) observati…

WISDOM Project -- XIX. Figures of merit for supermassive black hole mass measurements using molecular gas and/or megamaser kinematics

Hengyue Zhang, Martin Bureau, Mark D. Smith +7

The mass () of a supermassive black hole (SMBH) can be measured using spatially-resolved kinematics of the region where the SMBH dominates gravitationally. The most…

WISDOM Project -- XXVI. Cross-checking supermassive black hole mass estimates from ALMA CO gas kinematics and SINFONI stellar kinematics in the galaxy NGC 4751

Pandora Dominiak, Michele Cappellari, Martin Bureau +6

We present high angular resolution ( or pc) ALMA observations of the CO(3-2) line emission of the galaxy NGC 4751. The data provide evidence for the pres…

WISDOM project -- XVIII. Molecular gas distributions and kinematics of three megamaser galaxies

Fu-Heng Liang, Mark D. Smith, Martin Bureau +11

The co-evolution of galaxies and supermassive black holes (SMBHs) underpins our understanding of galaxy evolution, but different methods to measure SMBH masses have only infrequent…

WISDOM Project -- XVII. Beam-by-beam Properties of the Molecular Gas in Early-type Galaxies

Thomas G. Williams, Martin Bureau, Timothy A. Davis +9

We present a study of the molecular gas of seven early-type galaxies with high angular resolution data obtained as part of the mm-Wave Interferometric Survey of Dark Object Masses…

A fundamental plane of black hole accretion at millimetre wavelengths

Ilaria Ruffa, Timothy A. Davis, Jacob S. Elford +11

We report the discovery of the ``mm fundamental plane of black-hole accretion'', which is a tight correlation between the nuclear 1 mm luminosity (), the intrinsic $…

Dynamical Masses and Ages of Sirius-like Systems

Hengyue Zhang, Timothy D. Brandt, Rocio Kiman +4

We measure precise orbits and dynamical masses and derive age constraints for six confirmed and one candidate Sirius-like systems, including the Hyades member HD 27483. Our orbital…

Cleaning Images with Gaussian Process Regression

Hengyue Zhang, Timothy D. Brandt

Many approaches to astronomical data reduction and analysis cannot tolerate missing data: corrupted pixels must first have their values imputed. This paper presents astrofix, a rob…
