[Guest] The Walking Red: Why are you so quiet and overdense?
Why do we see so many massive, dead galaxies at early cosmic times? Guest author Tatevik Mkrtchyan illuminates a slice of the cosmic graveyard!
Dancing with the Blazars: Variability you can groove to
In today’s paper, we explore how blazar light curves can be transformed into music and the benefits of this for both scientists and science communication.
FIREstorms in early galaxies: Simulating the brief, blazing lives of giant clumps
What do a galaxy’s stellar clumps tell us about how it formed? Today’s guest author Michelle Park explores interesting properties of clumps from the FIRE simulations.
Guest: Teaching Machines to Spot Star‑Forming Clumps in Galaxies
Clumpy galaxies dominate the early universe, yet their local counterparts are hard to find. A new machine‑learning approach learns to spot these hidden clumps and opens the door to studying them in far greater detail.
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
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!
