HARMONI for the ELT

In preparation.

Resolved stellar populations in nearby galaxies

The metallicities and kinematics of individual stars will be studied in the nuclear bulge of the Milky Way and in nearby objects up to 4 Mpc Gonzalez & Battaglia 2018

Emission-line galaxies at z~2-3

HARMONI is to spatially resolve the interstellar medium (ISM) of high-redshift (z∼2-3) galaxies and measure the physical processes and kinematics occurring on scales of individual HII regions Zieleniewski et al. 2015

Stellar kinematics of high-z galaxies

Stellar absorption line integral field spectroscopy with HARMONI will reveal the stellar kinematics of galaxies at z=2-4 with M_★ > 10^10-10.7 M_☉ Kendrew et al. 2015

High-z supernovae classification

HARMONI will classify Type Ia supernovae at z~3 up to 80 days past the maximum light Bounissou et al. 2018

Black Hole-Galaxy Scaling Relation Evolution at z~2.5

Parameters such as the morphology and kinematics of the host galaxies of high-z quasars will be derived with HARMONI García-Lorenzo et al. 2019

Emission from the circumgalactic medium

The circumgalactic medium traced by the Lyα, Hα, CIV, or OVI transitions will be detected by HARMONI up to z~4 Augustin et al. 2019

Ionized gas kinermatics at z~1.5

Based on a model galaxy from the NUTFB cosmological simulation, HARMONI will be able to recover the rotation curve a of an ~L_★ galaxy with a star-formation rate of 3 M_☉/yr at z~1.5 in 1 hour Richardson et al. 2020

Population III stars

Using the He IIλ1640 emission line, HARMONI will be able to detect Pop. III stars in galaxies up to z ∼ 10 provided the initial mass function (IMF) is top heavy. If the IMF is similar to Pop. I stars, HARMONI will detect Pop. III stars at z ~ 4 in objects with M_★ > 10⁷ M_☉ Grisdale et al. 2021
