UR: Data-Driven Analysis of Galactical Evolution
In the latest of our #UndergradResearch series, discover how to estimate the metallicities of early galaxies using line ratios from JWST with Vidit Bhandari.
Hats Off to a Spectroscopic Study of Sombrero Galaxy Globular Clusters
You really have to tip your hat to the authors of today’s bite, who closely studied the dynamics and metallicities of the globular clusters of M104.
Twinkle, twinkle, little quasar! Can you tell me how far away you are?
When we don’t have spectra, we can estimate the distance to a quasar by calculating its photometric redshift. Today’s authors present a new way to use the ‘flickering’ of quasars to improve these distance estimates.
Roman Spectroscopy Data Challenge Splinter Session at AAS246
Guest authors from the Nancy Grace Roman Space Telescope’s Spectroscopic Probes of Quantitative Reionization (SPQR) Team takes us through the upcoming Roman Spectroscopy Data Challenge at the 246th AAS Splinter Session.
Duel of the Dual: The Mystery of a Quasar Pair
Today’s paper explores a binary quasar system that’s full of mysteries!
J1010+2358 PISN’t a direct descendant of the first stars
We thought we finally found a direct descendant of the first stars. A follow-up observation showed that it PISN’t.
