Possibility of Using 3.3 μm Polycyclic Aromatic Hydrocarbon Luminosity as a Molecular Gas Mass Estimator

The Astrophysical Journal
We present CO(1–0) observations of 50 star-forming galaxies at 0.01 < z < 0.35, for which 3.3 μ m polycyclic aromatic hydrocarbon (PAH) emission flux or its upper limit is available.

Ionized Carbon in Galaxies: The [C ii] 158 μm Line as a Total Molecular Gas Mass Tracer Revisited

The Astrophysical Journal
In this paper, we present a statistical study of the [C ii ] 158 μ m line and the CO(1−0) emission for a sample of ∼200 local and high- z (32 sources with z > 1) galaxies with very different physical conditions.

Implication of Galaxy-scale Negative Feedback by One of the Most Powerful Multiphase Outflows in a Hyperluminous Infrared Galaxy at Intermediate Redshift

The Astrophysical Journal
Powerful galactic outflows driven by active galactic nuclei (AGNs) are commonly considered as one of the main mechanisms to regulate star formation in massive galaxies.

Discovery of Powerful Multivelocity Ultrafast Outflows in the Starburst Merger Galaxy IRAS 05189–2524 with XRISM

The Astrophysical Journal Letters
We observed the X-ray-bright ultraluminous infrared galaxy IRAS 05189−2524 with XRISM during its performance verification phase. The unprecedented energy resolution of the onboard X-ray microcalorimeter revealed complex spectral features at ∼7–9 keV ...
