Ever deeper and wider look-back surveys have led to a fairly robust outline of the cosmic
star-formation history, which culminated around; this period is often nicknamed “cosmic …

Astronomical observations reveal a major deficiency in our understanding of physics—the
detectable mass is insufficient to explain the observed motions in a huge variety of systems …

Galaxies with stellar masses as high as roughly 1011 solar masses have been identified,–
out to redshifts z of roughly 6, around 1 billion years after the Big Bang. It has been difficult to …

We report on the discovery of two low-luminosity, broad-line active galactic nuclei (AGNs) at
z> 5 identified using JWST NIRSpec spectroscopy from the Cosmic Evolution Early Release …

We present PHANGS–ALMA, the first survey to map CO J= 2→ 1 line emission at∼ 1''∼ 100
pc spatial resolution from a representative sample of 90 nearby (d≲ 20 Mpc) galaxies that lie …

The study of galaxy evolution hinges on our ability to interpret multiwavelength galaxy
observations in terms of their physical properties. To do this, we rely on spectral energy …

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 introduce SPARC (Spitzer Photometry and Accurate Rotation Curves): a
sample of 175 nearby galaxies with new surface photometry at 3.6 μm and high-quality …

Broadband photometry of galaxies measures an unresolved mix of complex stellar
populations, gas, and dust. Interpreting these data is a challenge for models: many studies …
