A Glimpse of the Stellar Populations and Elemental Abundances of Gravitationally Lensed, Quiescent Galaxies at z ≳ 1 with Keck Deep Spectroscopy

open access: yesThe Astrophysical Journal, 2023
Gravitational lenses can magnify distant galaxies, allowing us to discover and characterize the stellar populations of intrinsically faint, quiescent galaxies that are otherwise extremely difficult to directly observe at high redshift from ground-based ...

The four-loop cusp anomalous dimension from the N=4 Sudakov form factor

open access: yesPhysics Letters B, 2020
We present an analytic derivation of the full four-loop cusp anomalous dimension of N=4 supersymmetric Yang-Mills theory from the Sudakov form factor. To extract the cusp anomalous dimension, we calculate the ϵ−2 pole of the form factor using parametric ...

Elemental Abundances of the Super-Neptune WASP-107b’s Host Star Using High-resolution, Near-infrared Spectroscopy

open access: yesThe Astrophysical Journal, 2023
We present the first elemental abundance measurements of the K dwarf (K7V) exoplanet-host star WASP-107 using high-resolution ( R ≃45,000), near-infrared ( H - and K -band) spectra taken from Gemini-S/IGRINS.

MOSEL Survey: JWST Reveals Major Mergers/strong Interactions Drive the Extreme Emission Lines in the Early Universe

open access: yesThe Astrophysical Journal Letters, 2023
Extreme emission line galaxies (EELGs), where nebular emissions contribute 30%–40% of the flux in certain photometric bands, are ubiquitous in the early Universe ( z > 6).

Christián Carman and Rodolfo P. Buzón, Aristarco de Samos

open access: yesAestimatio, 2022
: This work by Aristarchus belongs to ancient science, which may be considered in three fields of development: ∘ mathematics, especially that focused on the geometry in Euclid’s Elements or Archimedes’ works; ∘ astronomy, understood as a science that ...
