EFFECT OF GALAXY ENVIRONMENT ON AGNs AND LAEs
The role of the galaxy environment in the active galactic nucleus (AGN) and Lyman-alpha emitter (LAE) activities is still a mystery. My research during my master's aimed to shed light on this problem by investigating nearby galaxies observed by the AKARI infrared telescope and high-redshift LAEs observed by Subaru Hyper-Suprime Cam (HSC).
Read my work on galaxy environment and AGNs [Santos et al. (2021b)], and LAEs [Santos et al. (2022)].

RESOLVING THE BLR OF BLACK HOLES
My PhD project focuses on resolving the broad line regions (BLRs) of nearby active galactic nuclei (AGNs) with GRAVITY, the second-generation near-infrared beam combiner at the Very Large Telescope Interferometer. This project aims to gain a further understanding of the physics behind the BLR, a mystery that is yet to be solved.

(2) On the preparatory spectroscopic survey of cosmic-noon AGNs for GRAVITY+ observations: Santos et al. 2025

WHY IS ASTRO-PH IMPORTANT FOR ASTRONOMY EDUCATION?
Astro-ph, or Astro-Coffee (AC), is a journal club formed and lead by astronomy institutes around the world. The goal of AC varies from institute to institute, but its main purpose is to keep track of the latest findings in astronomy research. My research during my master's aim to pinpoint the important factors that affect the success of implementing AC.
