A Relationship between Nuclear Black Hole Mass and Galaxy Velocity Dispersion [PDF]
, 2000 We describe a correlation between the mass Mbh of a galaxy's central black hole and the luminosity-weighted line-of-sight velocity dispersion σe within the half-light radius.

The Demography of Massive Dark Objects in Galaxy Centers [PDF]
, 1997 We construct dynamical models for a sample of 36 nearby galaxies with Hubble Space Telescope (HST) photometry and ground-based kinematics. The models assume that each galaxy is axisymmetric, with a two-integral distribution function, arbitrary ...

Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We use cosmological simulations of isolated Milky Way (MW)-mass galaxies, as well as Local Group (LG) analogues, to define the ‘edge’ – a caustic manifested in a drop in density or radial velocity – of Galactic-sized haloes, both in dark matter and in stars.

PlantTribes2: Tools for comparative gene family analysis in plant genomics
Frontiers in Plant Science, 2023 Plant genome-scale resources are being generated at an increasing rate as sequencing technologies continue to improve and raw data costs continue to fall; however, the cost of downstream analyses remains large.

The Galaxy in Context: Structural, Kinematic, and Integrated Properties [PDF]
, 2016 Our Galaxy, the Milky Way, is a benchmark for understanding disk galaxies. It is the only galaxy whose formation history can be studied using the full distribution of stars from faint dwarfs to supergiants.

Gaia DR2 Distances to Planetary Nebulae
Galaxies, 2020 The aim of this work is to examine distances to planetary nebulae (PNe) together with other properties that were derived from them, using the astrometry of Gaia Data Release 2 (DR2).

Detailed Structural Decomposition of Galaxy Images [PDF]
, 2002 We present a two-dimensional fitting algorithm (GALFIT) designed to extract structural components from galaxy images, with emphasis on closely modeling light profiles of spatially well-resolved, nearby galaxies observed with the Hubble Space Telescope ...

CIGALE: a python Code Investigating GALaxy Emission [PDF]
Astronomy & Astrophysics, 2018 Context. Measuring how the physical properties of galaxies change across cosmic times is essential to understand galaxy formation and evolution. With the advent of numerous ground-based and space-borne instruments launched over the past few decades we ...
