The Detection of H2O Maser Emission from Mid-IR Red Galaxies

The Detection of H2O Maser Emission from Mid-IR Red Galaxies

We report the detection of H _2 O maser emission in 4 out of 77 (5.2%) mid-IR red galaxies that meet the color criteria of W 1 − W 2 > 0.5 and W 1 − W 4 > 7 and are classified as Type 2 active galactic nuclei (AGNs) based on optical, near-IR, and mid-IR spectral energy distribution (SED) fitti...
