Mass models of galaxy clusters from a non-parametric weak-lensing reconstruction
Tobias Mistele, Federico Lelli, Stacy McGaugh +2
We study the CLASH sample of galaxy clusters using a new deprojection method for weak gravitational lensing observations. This method is non-parametric, allowing us to infer mass p…
A New Uncertainty Scheme for Galaxy Distances from Flow Models
Konstantin Haubner, Federico Lelli, Enrico Di Teodoro +3
The systemic velocity or redshift of galaxies is a convenient tool to calculate their distances in the absence of primary methods, but the uncertainties on these flow distances may…
Galaxy clusters in Milgromian dynamics: Missing matter, hydrostatic bias, and the external field effect
Ruth Kelleher, Federico Lelli
We study the mass distribution of galaxy clusters in Milgromian dynamics, or modified Newtonian dynamics (MOND). We focus on five galaxy clusters from the X-COP sample, for which h…
Measuring galaxy cluster mass profiles into the low acceleration regime with galaxy kinematics
Pengfei Li, Yong Tian, Mariana P. Júlio +7
We probe the dynamical mass profiles of 10 galaxy clusters from the HIghest X-ray FLUx Galaxy Cluster Sample (HIFLUGCS) using galaxy kinematics. We numerically solve the spherical…
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…
A scaling-relation for disc galaxies: circular-velocity gradient versus central surface brightness
Federico Lelli, Filippo Fraternali, Marc Verheijen
For disc galaxies, a close relation exists between the distribution of light and the shape of the rotation curve. We quantify this relation by measuring the inner circular-velocity…
Dynamics of Starbursting Dwarf Galaxies. II. UGC 4483
Federico Lelli, Marc Verheijen, Filippo Fraternali +1
UGC 4483 is a nearby Blue Compact Dwarf (BCD) galaxy. HST observations have resolved the galaxy into single stars and this has led to the derivation of its star formation history a…
Dynamics of Starbursting Dwarf Galaxies: I Zw 18
Federico Lelli, Marc Verheijen, Filippo Fraternali +1
I Zw 18 is a prototype Blue Compact Dwarf (BCD), characterized by a strong starburst and extremely low metallicity (Z ~ 0.02 Zsun). It has long been considered a candidate young ga…
Structure and dynamics of giant low surface brightness galaxies
Federico Lelli, Filippo Fraternali, Renzo Sancisi
Giant low surface brightness (GLSB) galaxies are commonly thought to be massive, dark matter dominated systems. However, this conclusion is based on highly uncertain rotation curve…
