Thursday Astrophysics Lunch Seminar (TALuS)
Regular meetings are held for astronomy-connected members of the physics department each Thursday in the 12th floor lounge from 11:45am–1pm. Sandwiches are provided. The local astrophysics faculty (Allen, Duez, Worthey, and–when he’s in town–Bose) are present. Graduate students engaged or interested in astrophysics research are welcome, as are undergraduates doing thesis work in astronomy. We discuss astronomy news as well as other topics relevant to astronomy research and teaching at WSU.
We’ll be meeting at the regular time and place. Some interesting reading:
measuring the mass of an imaged planet (from its star’s proper motion, if you can believe it)
matter observed falling straight into a black hole (implications for chaotic accretion)
evidence that the jet did break out in GW170817
Astronomy lunch will meet at the usual time and place.
Some self-help from astrobites: What does success mean to you? and the Conference survival guide for students. Also from them, how about an excuse to look at ALMA images of protoplanetary disks? It never get old.
Welcome to the new semester.
Come join us to discuss the summer’s astro news. I’ll have to think back to remember it. Here are some things that come right to mind.
neutrinos detected from an AGNRead Story
Can gravitational waves settle the Hubble constant debate?
strong cosmic censorship disproven?
the mission to “touch the sun”

Good luck to our students taking oral exams or traveling to the April APS meeting! (We’ll want a full report next week from those of you attending the meeting.)Read Story
TALuS 4/5/2018 — cancelled
No astro seminar this week because of comprehensive exams. Good luck, graduate students!
Some reading material anyway:

This week postdoc Fatemeh Nouri will be visiting from Pune. Here is her most recent paper: https://arxiv.org/abs/1710.07423

Welcome back from spring break! We’ll be meeting again at the regular time and place to discuss astronomy and gravitational physics.

Juno on Jupiter’s jet streams. We also discussed Jupiter’s Red Spot: Here is a nice video explaining why turbulence tends to be confined to 2D in a rotating frame:

We’re on for this week. Topics of discussion include the stuff we didn’t get a chance to talk about last week (see last week’s post) plus some new additions.
