- Preliminary Exam
- The Physical Characteristics of Faint, High-redshift Dusty Star-forming Galaxies
- Time: 2:00 pm - 4:00 pm
- Place: Sterling Hall, Room B343
- Speaker: Stephen McKay, Physics PhD Graduate Student
- Abstract: Once entirely undetected in large galaxy surveys, dusty star-forming galaxies (DSFGs)--a population of massive, dust-enshrouded galaxies with prodigious star formation rates (SFRs)--contribute heavily to the cosmic star formation history at high redshifts (z ≳ 1). However, since their original detection nearly three decades ago as submillimeter galaxies (or SMGs), a detailed understanding of these galaxies has been extremely difficult to obtain for large samples, in particular for faint sources that fall below typical wide-field survey limits. In this talk, I will discuss my work on inferring the multiwavelength properties of large samples of high-redshift DSFGs using observations with the Atacama Large Millimeter/submillimeter Array (ALMA) and the James Webb Space Telescope (JWST). I will describe how my work will shed light on crucial characteristics of the faint DSFG population, including their dust content, stellar populations, ongoing star formation, molecular gas, and, ultimately, their obscured contribution to the Universe's star formation history across cosmic time.
- Host: Amy Barger, Vernon Barger
- Department Coffee Hour
- Physics Cookie Potluck
- Time: 2:00 pm - 3:00 pm
- Place: University Ave steps or (in case of bad weather) 2120 CH
- Abstract: Let’s celebrate the end of the semester and kick off the summer with a cookie potluck! Bakers should bring a batch of their best to share! If you’re not a baker or don’t have time, just come hang out with us for a bit to have a cookie or two (we always have plenty!). For the bakers, it’d be helpful if you can mark your goodies with an allergens list (especially helpful to mark nuts/no nuts, dairy-free, gluten-free, etc.). If the weather’s nice, let’s gather outside on the front steps (overlooking University Ave). If it’s not so nice, look for us in 2120 CH.
