SLAS Regular Meeting

McDonnell Hall, Washington University - St. Louis

7:30pm Friday, April 19, 2024

 

 “4 Meter Telescope in Chile”

by

Gautham Narayan, PhD  ;  Univ of Illinois

 

Gautham Narayan received his PhD in Physics from Harvard University and is currently an Assistant Professor at the University of Illinois, Urbana-Champaign. His research interests are at the intersection of multi-messenger and time-domain astrophysics, cosmology, statistics and data science. He works on wide-field surveys developing machine learning methods for real-time detection and classification of variable and transient sources, Bayesian models for cosmological inference with type Ia supernovae, understanding the host galaxies of transients, and establishing an all-sky network of faint spectrophotometric standards for LSST, WFIRST and future projects.

 

Dr. Naravan is one of the organizers of Astronomy on Tap, Champaign-Urbana, and a former organizer of Astronomy on Tap, Tucson, does podcasts, public talks, panels at sci-fi conventions (Robots! Sci-fi space battles! Gustav Holst’s Planets suite and more!), volunteers with local STEM clubs, and works get people as excited about science as he is.

 

Dr. Naravan is Deputy Analysis Coordinator for LSST's Dark Energy Science Collaboration, and former convener of the Time Domain Working Group, co-PI of the Young Supernova Experiment. He am also a member of the SCiMMA Group, the LSST Transients and Variable Stars Science Collaboration, and has been a member of the Pan-STARRS, ESSENCE, Foundation, MzLS and RAISIN survey, among others.

 


The meeting will begin at 7:30 PM Friday, April 19 in McDonnell Hall, Room 162, on the Danforth campus of Washington University, Saint Louis, MO 63105.

Frequently Asked Questions (FAQ) – April 8, 2024 Total Solar Eclipse

 

When is the eclipse for Missouri? – The Solar Eclipse will occur early afternoon on Monday April 8, 2024. The Moon will start covering the Sun around 12:38pm CDT, this is called the partial phase of the eclipse. Totality begins when the moon has completely covered the Sun, this begins around 1:54pm CDT. The Moon will completely cover the Sun for up to 4 minutes and 10 seconds, depending on your location. After totality ends, the Moon will gradually uncover the Sun, and this partial eclipse will end around 3:14pm CDT. Precise times for cities and towns in Missouri can be found here: https://eclipse2024.org/eclipse_cities/total/mo

Where do I need to be to see the Totally Eclipsed Sun? – The immediate St. Louis area is NOT in the Total Eclipse Path. You must travel approximately 100 miles south or east to be inside the Total Eclipse Path. You must be inside the Total Eclipse Path to see the Moon completely cover (eclipse) the Sun. The center of this path runs from Texas to Maine, passing through: Texas, Arkansas, Missouri, Illinois, Indiana, Ohio, New York, Vermont and Maine. The Total Eclipse Path is around 120 miles wide in southeast Missouri. Outside this path you will only see a partial eclipse. Inside this path the Moon will completely block the Sun, allowing you to see the Sun’s inner and outer atmosphere and corona. Accurate maps can be found using these links:
