A Possible GLIMPSE of the Universe’s First Stars
Today’s bite explores a new method to find the galaxies hosting the Universe’s first generation of stars
She’s Not Like the Other Galaxies: The Nearly-Impossible Qualities of CEERS2-588
Galaxy-modelers beware! Today’s bite will guide you through an analysis of CEERS2-588, a quirky, UV-luminous, early galaxy discovered by JWST that’s causing issues in our theoretical models!
Standardizing Standard Candles: Exploring the (lack of a) Bias in Cosmological Distance Measurements
Today’s paper tests some recent claims that there is a bias in cosmological distance measurements!
MeerKAT meets a giga-maser!
Space is full of unusual and (sometimes) quite powerful phenomena that cause light to behave in unexpected ways. Maser systems are one of these phenomena. The MeerKAT Radio Telescope recently detected the most luminous and distant hydroxyl (or OH) maser system – so intense it crossed the threshold from “mega-maser” to “giga-maser”. Discover why this system is so remarkable in this bite!
Do we actually know how old the Universe is?
So we have a pretty good idea of how old the Universe is right? Well according to JWST data, maybe not? Rest assured, today’s bite gets to the bottom of the debate.
Feeding Time at the AGN Zoo
How do the eating habits (accretion) of active galactic nuclei (AGN) affect the light emitted for animals in the AGN zoo?
