The study of Population III star detectability led by former CSL undergraduate Mikaela Larkin was recently singled out as a Research Highlight by Nature Astronomy (read the highlight and the article).
The discovery of the shortest-period ultracool dwarf binary system, LP 413-53AB, by former CLS graduate student Dino Hsu using multiple epochs of Keck/NIRSPEC measurements, has been accepted for publication in Astrophysical Journal Letters (read the article on arxiv).
CSL undergraduate researchers earned top honors as recipients of the UCSD School of Physical Sciences Dean's Undergraduate Excellence Awards: Malina Desai, Juan Diego Draxl Giannoni, Natalie Lam, and Deliliah Jacobsen were among 34 recipients selected from other 4,000 physical science majors. Congratulations to our outstanding undergraduates!
Christian Aganze was selected as an honorable mention for the Bouchet Graduate Honor Society, co-founded in 2005 by Yale and Howard Universities and named for Edward Alexander Bouchet, the first African American doctoral recipient in the United States. Congratulations Christian!
The Cool Star Lab Machine Learning group recently published a Research Note demonstrating spectral binary identification with a random forest classifier. The paper was led by undergraduate researcher Malina Desai. (read the paper at RNAAS)
