- ItemThe Nature of Extreme Supernova Explosions(2010) Drake, Andrew; Mahabal, Ashish; Djorgovski, George; Christensen, Eric; Beshore, Edward; Catelan, Marcio; Prieto, JoseSupernovae provide important insight into the lives and deaths of stellar systems as well as being vital cosmological distance standards. This proposal is for spectroscopic follow-up of the extremely luminous events currently being discovered by the Catalina Real-time Transient Survey (CRTS). Like the large synoptic surveys of the future, the three telescopes CRTS employs to discover optical transients cover tens of thousands of square degrees on the sky each lunation. This coverage has so far enabled the discovery of well over 1200 distinct optical transient events including more than 330 supernovae. Among these supernovae at least a dozen are extremely luminous type IIn and pair- instability supernovae. In this work we hope to significantly increase the understanding of the nature of the supernova progenitors, as well as their host galaxies....

- ItemSupernovae in Extreme Environments(2012) Drake, Andrew J.; Prieto, Jose; Djorgovski, George; Mahabal, Ashish; Beshore, Edward; Graham, Matthew; Catelan, Marcio; Christensen, Eric; Stoll, RebeccaThe Catalina Real-time Transient Survey (CRTS) currently covers 33,000 square degrees of the sky in search of transient astrophysical events. Data provided by the Catalina Sky Survey provides an unequaled baseline against which more than 4000 unique optical transient events have been discovered and openly published in real-time. Of the more than 800 supernovae discovered among these are distinct classes of previously undetected extremely luminous type-Ic and type-IIn supernovae. These events appear to reside predominately in very faint, low-metalicity, star-forming galaxies. Similar to the environments that have been associated with so called hypernova explosions. However, the recent discovery of what was very likely the most luminous and optically energetic supernova ever discovered, CSS100217, within the AGN disk of a bright NLS1 galaxy, demonstrates that extreme supernova can occur in a variety of extreme environments. Here we propose to use Gemini observations to continue our study of the extreme supernova populations discovered by CRTS....

- ItemMath Talk Between Children and Mothers and Its Connection to Math-Related Practices in the Home Setting(2016) Susperreguy Jorquera, Maria InesEarly math skills are crucial for children's later achievement in school. These skills can be fostered by parents in informal contexts in the home in several ways. This chapter looks at how mothers and children talk about math during mealtimes, a context that has proved to promote opportunities for children to learn new words and information, and the links between math talk and math-related practices. Math talk (ie, talk about numbers, number operations, units of measure, or counting) occurring among mother–child dyads is described and analyzed as it occurs in natural exchanges in the home setting. The results show large variability in the frequency with which mothers and children engage in math talk at home. Math talk was also related to the math practices that mothers reported engaging in with their children 1 year later. The implications of these findings for families, teachers, and researchers are also discussed.
