We summarize what large surveys of the contemporary Universe have taught us about the
physics and phenomenology of the processes that link the formation and evolution of …

The spectral energy distributions (SEDs) of galaxies are shaped by nearly every physical
property of the system, including the star-formation history, metal content, abundance …

The mergers of binary compact objects such as neutron stars and black holes are of central
interest to several areas of astrophysics, including as the progenitors of gamma-ray bursts …

ABSTRACT I introduce some improvements to the ppxf method, which measures the stellar
and gas kinematics, star formation history (SFH) and chemical composition of galaxies. I …

Inference of the physical properties of stellar populations from observed photometry and
spectroscopy is a key goal in the study of galaxy evolution. In recent years, the quality and …

Nonparametric star formation histories (SFHs) have long promised to be the" gold standard"
for galaxy spectral energy distribution (SED) modeling as they are flexible enough to …

ABSTRACT We present Bayesian Analysis of Galaxies for Physical Inference and Parameter
EStimation, or bagpipes, a new python tool that can be used to rapidly generate complex …

I start by providing an updated summary of the penalized pixel-fitting (ppxf) method that is
used to extract the stellar and gas kinematics, as well as the stellar population of galaxies …

Deriving the expansion history of the Universe is a major goal of modern cosmology. To
date, the most accurate measurements have been obtained with Type Ia Supernovae (SNe) …

We measure a value for the cosmic expansion of H (z)= 89±23 (stat)±44 (syst) km s− 1 Mpc−
1 at a redshift of z≃ 0.47 based on the differential age technique. This technique, also known …
