The coherent motion of Cen A dwarf satellite galaxies remains a challenge for CDM cosmology
Oliver Müller, Marcel S. Pawlowski, Federico Lelli +6
The plane-of-satellites problem is one of the most severe small-scale challenges for the standard CDM cosmological model: several dwarf galaxies around the Milky Way and Androme…
The properties of dwarf spheroidal galaxies in the Cen A group: Stellar populations, internal dynamics, and a heart-shaped Halpha ring
Oliver Müller, Katja Fahrion, Marina Rejkuba +7
Dwarf spheroidal galaxies (dSphs) have been extensively investigated in the Local Group, but their low luminosity and surface brightness make similar work in more distant galaxy gr…
ALMA Resolves Giant Molecular Clouds in a Tidal Dwarf Galaxy
M. Querejeta, F. Lelli, E. Schinnerer +12
Tidal dwarf galaxies (TDGs) are gravitationally bound condensations of gas and stars formed during galaxy interactions. Here we present multi-configuration ALMA observations of J10…
Testing the Strong Equivalence Principle: Detection of the External Field Effect in Rotationally Supported Galaxies
Kyu-Hyun Chae, Federico Lelli, Harry Desmond +3
The strong equivalence principle (SEP) distinguishes General Relativity from other viable theories of gravity. The SEP demands that the internal dynamics of a self-gravitating syst…
Revealing the intermediate-mass black hole at the heart of the dwarf galaxy NGC 404 with sub-parsec resolution ALMA observations
Timothy A. Davis, Dieu D. Nguyen, Anil C. Seth +15
We estimate the mass of the intermediate-mass black hole at the heart of the dwarf elliptical galaxy NGC 404 using Atacama Large Millimeter/submillimeter Array (ALMA) observations…
Using The Baryonic Tully-Fisher Relation to Measure
James Schombert, Stacy McGaugh, Federico Lelli
We explore the use of the baryonic Tully-Fisher relation (bTFR) as a new distance indicator. Advances in near-IR imaging and stellar population models, plus precise rotation curves…
From spirals to lenticulars: evidence from the rotation curves and mass models of three early-type galaxies
Alexandra V. Shelest, Federico Lelli
Rotation curves have traditionally been difficult to trace for early-type galaxies (ETGs) because they often lack a high-density disk of cold gas as in late-type galaxies (LTGs). W…
A comprehensive catalog of dark matter halo models for SPARC galaxies
Pengfei Li, Federico Lelli, Stacy McGaugh +1
We present rotation curve fits to 175 late-type galaxies from the Spitzer Photometry & Accurate Rotation Curves (SPARC) database using seven dark matter (DM) halo profiles: pseudo-…
A first attempt to differentiate between modified gravity and modified inertia with galaxy rotation curves
Jonas Petersen, Federico Lelli
The phenomenology of modified Newtonian dynamics (MOND) on galaxy scales may point to more fundamental theories of either modified gravity (MG) or modified inertia (MI). In this pa…
Metal-poor nuclear star clusters in two dwarf galaxies near Centaurus A suggesting formation from the in-spiraling of globular clusters
Katja Fahrion, Oliver Müller, Marina Rejkuba +7
Studies of nucleated dwarf galaxies can constrain the scenarios for the formation and evolution of nuclear star clusters (NSC) in low-mass galaxies and give us insights on the orig…
