A Note on Compactness and Clique Size
David V. Feldman, Alexander Wilce
Say that a topological space has finite, respectively bounded, cliques iff every closed, irreflexive binary relation --- equivalently, every closed, loop-free directed graph --…
An automated method for planetary nebula detection with SIGNALS: first applications to NGC 4214 and NGC 4449
Nancy Yang, Johanna Hartke, Martin Bureau +11
Utilising the optical imaging Fourier transform spectrograph SITELLE, the Star-formation, Ionized Gas and Nebular Abundances Legacy Survey (SIGNALS) is designed to study the connec…
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…
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 -- 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…
