CLEAR: The Morphological Evolution of Galaxies in the Green Valley
The Astrophysical Journal, 2023 Quiescent galaxies having more compact morphologies than star-forming galaxies has been a consistent result in the field of galaxy evolution. What is not clear is at what point this divergence happens, i.e., when do quiescent galaxies become compact, and

OPTICAL SPECTROSCOPY OF DISTANT RED GALAXIES [PDF]
The Astrophysical Journal, 2009 We present optical spectroscopic follow-up of a sample of Distant Red Galaxies (DRGs) with K < 22.5 (Vega), selected by J-K > 2.3, in the Hubble Deep Field South, the MS 1054-03 field, and the Chandra Deep Field South. Spectroscopic redshifts were obtained for 15 DRGs. Only 2 out of 15 DRGs are located at z < 2, suggesting a high efficiency to

The Origin of Star-forming Rings in S0 Galaxies
The Astrophysical Journal, 2023 Spatially resolved integral field spectroscopic maps in a sample of 532 S0 galaxies from the MaNGA survey have unveiled the existence of inner rings (〈 R 〉 ∼ 1 R _e ) betraying ongoing star formation in a number of these objects.

Herschel Spectroscopy of Early-type Galaxies [PDF]
The Astrophysical Journal, 2017 Abstract We present Herschel spectroscopy of atomic lines arising in photodissociation regions as well as ionization regions of nearby early-type galaxies (ETGs), focusing on the volume-limited Atlas3D sample. Our data include the [C ii], [O i], and [N ii] 122 and 205 μm lines, along with ancillary data including CO and H i maps. We find

SPIRE Spectroscopy of Early-type Galaxies [PDF]
The Astrophysical Journal, 2019 Abstract We present Spectral and Photometric Imaging Receiver (SPIRE) spectroscopy for nine early-type galaxies (ETGs) representing the most CO-rich and far-infrared (FIR) bright galaxies of the volume-limited Atlas3D sample. Our data include detections of mid- to high-J CO transitions (J = 4–3 to J = 13–12) and the [C i] (1–0) and (2–1)

Optical spectroscopy of southern radio galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1993 We present optical spectroscopy of 11 radio galaxies, using the Anglo-Australian Telescope. Redshifts are measured for the seven radio galaxies with no previously published values, and for the other four which have uncertain ...

Can Cosmological Simulations Reproduce the Spectroscopically Confirmed Galaxies Seen at z ≥ 10?
The Astrophysical Journal Letters, 2023 Recent photometric detections of extreme ( z > 10) redshift galaxies from the JWST have been shown to be in strong tension with existing simulation models for galaxy formation and in the most acute case, in tension with ΛCDM itself.
