Name: Isha Nayak
Title: Multi-Wavelength Analysis of a Super Star Cluster
Abstract: The Large Magellanic Cloud has been the subject of star formation studies for decades due to its proximity to the Milky Way (50 kpc), a nearly face-on orientation, and a low metallicity (0.5 solar) similar to that of galaxies at the peak of star formation in the universe (z~2). A newly discovered super star cluster candidate (H72.97-69.39) located in the N79 region of the Large Magellanic Cloud has a luminosity of over 2,000,000 L_sun, making it one of the brightest compact sources ever to be observed. Super star clusters are rare in the local Universe. The discovery of H72.97-69.39 gives us a rare opportunity to study such an extreme object during its initial forming stage. I analyze ALMA CO molecular gas clouds around this super star cluster candidate and find evidence of colliding filaments, outflows, and even rotation. I use ancillary SOFIA data and Magellan FIRE data to constrain the outflow rate from the massive protostars, constrain the temperature of the gas, determine the spectral type of the young stellar objects, and estimate the extinction. Looking at the interplay between dense molecular gas and the newly forming stars will shed light on the formation mechanism: filamentary collision, core accretion, or competitive accretion. My current work using ALMA observations of a super star cluster candidate in N79 serves as the basis for JWST MIRI and NIRCam planned GTO observations.

Name: Invision Working Group
Title: The Status of Diversity & Inclusion at STScI
Abstract:  The members of the STScI Invision Working Group will present progress and results from projects and initiatives undertaken over the past year. This discussion will include, but will not be limited to, the following initiatives: establishing the STScI Meeting Code of Conduct, evaluating accessibility at the Institute, starting and maintaining the Invision Reading Group, analyzing the AURA climate survey results and results from subsequent focus groups, organizing the Inclusive Astronomy 2 Conference, and developing a Baltimore-centric mentorship and outreach infrastructure for Institute-wide use.
Context: The STScI Invision Working Group is a committee constituted within STScI to establish and uphold a civil and inclusive environment for a diverse staff. The working group will help to develop and ensure policies and practices that create a welcoming and productive work environment, and report to the Director's Office. The working group will identify issues and develop and recommend solutions to improve the work environment, enabling staff to best meet the needs of STScI's missions in a respectful, inclusive, and professional manner. This will include issues that have their root in various aspects of inclusion and culture differences, including such elements as gender identity or expression, sexual orientation, race, ethnic and cultural background, religion, educational background, age, people with disabilities, and occupation. The working group will consist of a broad cross-section of STScI staff, and members will be responsible for becoming familiar with and advocating for the concerns and ideas of the STScI staff.
