Over the last decade, ALMA has revolutionized our understanding of the interstellar medium (ISM) conditions of distant galaxies. For one, ALMA has now detected (sub-)millimeter continuum emission from dozens of galaxies at z > 6.5, establishing the importance of dust-obscured star formation already within the first 800 Myr after the Big Bang. Moreover, through various bright emission line diagnostics such as [CII]158 and [OIII]88, ALMA can be used to directly study the physical conditions and kinematics of the ISM within the earliest galaxies.
In this talk, I will review what we have learned about the dust and interstellar medium properties of high-redshift galaxies, focusing specifically on the Cycle 7 ALMA Large Program REBELS and its follow-up studies. In addition, I will present recently taken JWST/NIRSpec IFU observations of REBELS sources and discuss how we can use the combined power of ALMA and JWST to learn about early dust build-up in galaxies.
