Observations of hydroxyl in early-type galaxies
07 Aug 2025 Atlas3D 2nd author McBride OH Arecibo GBT

Observations of hydroxyl in early-type galaxies

This paper is quite special to me, because it was a fishing expedition that seemed unlikely to detect anything, and then nature and the universe
The ATLAS3D Project - XIV. The extent and kinematics of the molecular gas in early-type galaxies
04 Aug 2025 Atlas3D 2nd author Davis Early Types Annie Jump Cannon SAURON

The ATLAS3D Project - XIV. The extent and kinematics of the molecular gas in early-type galaxies

We continue our exploration of the molecular gas properties of early-type galaxies, which I have already blogged about here, here, and here. In this case,
Evidence of boosted 13CO/12CO ratio in early-type galaxies in dense environments
04 Aug 2025 Atlas3D 1st author Early Types CARMA IRAM 30m 13CO 12CO

Evidence of boosted 13CO/12CO ratio in early-type galaxies in dense environments

Last blog we learned about the strange things happening to gas in dense environments, like the Virgo cluster. This blog, we are going to continue
The ATLAS3D Project - X. On the origin of the molecular and ionized gas in early-type galaxies
04 Aug 2025 Atlas3D 2nd author Davis CARMA Early Types IFU Spectroscopy 12CO

The ATLAS3D Project - X. On the origin of the molecular and ionized gas in early-type galaxies

As the last blog talked about, we start with the Hubble tuning fork (Edwin Hubble published this in 1936, which is pretty amazing given how
The ATLAS3D project - XVIII. CARMA CO imaging survey of early-type galaxies
03 Aug 2025 Atlas3D 1st author Early Types CARMA 12CO

The ATLAS3D project - XVIII. CARMA CO imaging survey of early-type galaxies

It is time to change gears from AGN outflows and the different ways that they impact galaxy evolution to the important question of why do
Escape, Accretion, or Star Formation? The Competing Depleters of Gas in the Quasar Markarian 231
03 Aug 2025 Mrk231 1st author CARMA HST NGC1266 12CO Molecular Outflows

Escape, Accretion, or Star Formation? The Competing Depleters of Gas in the Quasar Markarian 231

This paper came about because I had a set of beautiful unpublished data from CARMA that needed to be given its due credit, and I
