Title: "Cooling Radiation From the First Protostars - A New Cosmic Background Signal"
There are universal astrophysical processes that produce important universal cosmic backgrounds such as the cosmic microwave background, cosmic infrared background and epoch of reionization signal. As these backgrounds produce radiation that fills the Universe, they may be detected as a surface brightness signal, which fills the beam of a telescope of any size and therefore may potentially be detectable even with a small telescope. This talk will consider the possibility of detection of a new cosmic background associated with the formation of the first protostars, arguing that this background is likely to appear as emission in the far infrared (20-100 micrometers) with a unique spectral and spatial signature that may be within the resolution and sensitivity of modest instruments.
Colloquia for the Fall 2020 semester will be held on zoom. Contact Prof. Alberto Bolatto for details.
