How old is that galaxy, really? Constraining the color-redshift relation with DESI
Today’s authors present a dataset that seeks to improve our understanding of the ages of faraway galaxies.
Uh oh, where did the atmosphere go: the impact of host stars’ radiation on exoplanet atmospheres
Today’s post tells you how planets can lose their atmospheres due to a star’s radiation – and what this means for exoplanets we have already found!
Looking for a Dragonfly in the sky!
What is the highest energy place in the Milky Way? Today’s paper looks at one of the contestants for this award: the Dragonfly nebula!
Can we identify the host galaxies of LISA sources?
The upcoming LISA mission promises to detect many gravitational wave events, but can it attribute any of them to a host galaxy? Let’s find out!
Horse(head)s in the Galactic Ecosystem
All galaxies are a complex ecosystem of interactions between hydrogen gas and stars. In today’s paper, the authors look at the Horsehead Nebula to narrow down the details of those interactions.
Tracing Star Fuel in the Universe’s Smallest Galaxies
It’s really hard to see molecular hydrogen (the fuel that makes stars) directly, so astronomers have to use other spectral lines to guess how much is there. In today’s paper, the authors discuss how to do that in the smallest galaxies in the universe!
