The Infrared Emission and Vigorous Star Formation of Low-redshift Quasars
Yanxia Xie, Luis C. Ho, Ming-Yang Zhuang +1
The star formation activity of the host galaxies of active galactic nuclei (AGNs) provides valuable insights into the complex interconnections between black hole growth and galaxy…
A Method to Extract Spatially Resolved Polycyclic Aromatic Hydrocarbon Emission from Spitzer Spectra: Application to M51
Lulu Zhang, Luis C. Ho, Yanxia Xie
The mid-infrared spectrum contains rich diagnostics to probe the physical properties of galaxies, among which the pervasive emission features from polycyclic aromatic hydrocarbons…
A New Calibration of Star Formation Rate in Galaxies Based on Polycyclic Aromatic Hydrocarbon Emission
Yanxia Xie, Luis C. Ho
Polycyclic aromatic hydrocarbon (PAH) emission has long been proposed to be a potential star formation rate indicator, as it arises from the photodissociation region bordering the…
Interstellar Medium and Star Formation of Starburst Galaxies on the Merger Sequence
Jinyi Shangguan, Luis C. Ho, Ruancun Li +3
The interstellar medium is a key ingredient that governs star formation in galaxies. We present a detailed study of the infrared (~ 1-500 micron) spectral energy distributions of a…
The Widespread Presence of Nanometer-size Dust Grains in the Interstellar Medium of Galaxies
Yanxia Xie, Luis C. Ho, Aigen Li +1
Interstellar dust spans a wide range in size distribution, ranging from ultrasmall grains of a few Angstroms to micrometer-size grains. While the presence of nanometer-size dust gr…
A New Technique for Measuring Polycyclic Aromatic Hydrocarbon Emission in Different Environments
Yanxia Xie, Luis C. Ho, Aigen Li +1
We present a new method to decompose the emission features of polycyclic aromatic hydrocarbons (PAHs) from mid-infrared spectra using theoretical PAH templates in conjunction with…
