The Fraction of Dust Mass in the Form of PAHs on 10-50 pc Scales in Nearby Galaxies
Polycyclic aromatic hydrocarbons (PAHs) are a ubiquitous component of the interstellar medium (ISM) in z~0 massive, star-forming galaxies and play key roles in ISM energy balance, chemistry, and shielding.

The Kinematics of Polycyclic Aromatic Hydrocarbons (PAHs) in Galaxies revealed by Principal Component Analysis (PCA) tomography with JWST/NIRSpec
Polycyclic Aromatic Hydrocarbons (PAHs) are organic molecules which comprise the smallest particles of dust in the interstellar medium (ISM). Due to their broad/complex emission profiles, obtaining kinematics is a challenge […]

Exploring Extremes In The Search For Life On Mars
People might assume the search for life on Mars ended when NASA’s first rovers sent back images of the planet’s barren, inhospitable surface. However, as scientists broaden their understanding of […]
![The parameter region of the AWDM. The correct baryon asymmetry can be obtained in the blue band. The region favored by the homochirality of the amino acids is represented by the red band. Here we use ξB = 0.1 − 10 while ξAA = 0.01 − 100. The gray (light gray) region is excluded by the observation relevant to the X-ray emission adopted from [39] (phase-space bound).
