Extragalactic astronomy, astronomical instrumentation, and precision optics.
From the observed sky to the instruments that make it work. Our team consists of young, multidisciplinary personnel — astronomers and astrophysicists, research assistants, optomechanical engineers, mechanical engineers, and full-stack developers. We are tackling challenges in astronomical research on two fronts: novel research methods and cutting-edge instrumentation technology.
One team, two workshops
SEAL × OTTER is the joint effort of SEA OtTeRS and SEAL Lab: one loop from the sky to the instrument and back. SEA OtTeRS defines the science and the observing cadence; the instruments it needs are designed, machined, and measured at SEAL Lab; the optics then go back on the telescopes, where the next survey begins.
Telescopes
2.4-m TNT, the 0.7-m TRT network across four continents, GTC, JWST and SDSS archives.
Science
Galaxy evolution at high redshift, AGN variability and reverberation mapping, machine-learning inference on survey data.
Instruments
CoLoRS and LRS spectrographs, robotic autoguiding and control, CubeSat mirrors.
Ultra-precision optics
5-axis diamond turning to Ra < 5 nm, interferometry, coating, and cryo-testing under one roof.
Featured projects
Three things the team is building or running right now. See all projects and facilities →
SPDT Engineering, Assembly, and Laser Metrology Laboratory
Thailand's first ultra-precision reflective-surface laboratory: 5-axis single-point diamond turning, surface metrology, and a complete design-to-metrology production line for metallic and freeform optics.
ARRAKIHS mission simulations
Mission simulations and mock observations for ESA's ARRAKIHS dark-matter space telescope; NARIT is the first Thai institute in an approved ESA mission.
Compact Low-Resolution Spectrograph for the 0.7-m Thai Robotic Telescopes
Single long-slit spectrograph with dichroic-split iz-band guiding for fully robotic transient classification and AGN reverberation monitoring on the 0.7-m TRT.
