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.
Today’s paper uses very deep JWST observations to hunt for some of the first galaxies ever formed!
JWST has found the first evidence of water ice in a Kuiper Belt around another star – and the water ice in this one bears a striking resemblance to that in our own Solar System’s Kuiper Belt.
Guest author Giovanni Cozzolongo tells us about peculiar pulsar magnetic fields!
By rewinding the orbits of hypervelocity stars, today’s authors discover something unusual about the Milky Way’s largest satellite galaxy.
Using X-ray observations from XMM-Newton, this paper studied the chemical makeup of the hot gas around the galaxy M86, which is being stripped as it moves through a cluster. They found that the galaxy’s core still holds onto its enriched gas, and that part of the stripped material likely comes from a past galaxy collision—not just the core being peeled away.
