The ALPINE-ALMA [CII] survey: Dust attenuation properties and obscured star formation at z~4.4-5.8

Understand

We present dust attenuation properties of spectroscopically confirmed star forming galaxies on the main sequence at a redshift of ~4.4-5.8.

• Our analyses are based on the far infrared continuum observations of 118 galaxies at rest-frame 158{\mu}m obtained with the Atacama Large Millimeter Array (ALMA) Large Program to INvestigate [CII] at Early times (ALPINE).
• We study the connection between the ultraviolet (UV) spectral slope ($\beta$), stellar mass (M_*), and infrared excess (IRX=L_IR/L_UV).
• Twenty-three galaxies are individually detected in the continuum at >3.5 sigma significance.
