Is our asteroid impact history wrong?! : Anomalous shock ages in meteorites from nonintuitive K and Ar behavior

Mara Karageozian, T. Sharp, M. Van Soest, C. McDonald

Abstract

Dating impacted meteorites helps us to understand the history of our solar system. But interpretations of Ar/Ar dating in melted samples isn't as straight forward as we think! Is 7 billions years too old for a meteorite?

Mapping and Interpreting the Northern Fan Deposit in Jezero Crater, Mars

Mohini J. Jodhpurkar, James F Bell III

Abstract

Jezero Crater is the landing site for NASA’s Perseverance mission, and as such it is important to gain as thorough of an understanding as is possible from orbital datasets before the rover lands. In addition to broadening our knowledge, the information collected pre-landing can also eventually be compared to the rover’s in situ observations. The northern fan deposit within the crater is of particular interest because it remains unclear whether it is related to the western delta or is its own system connected with the northern watershed. At the moment, it is also unclear whether the fluvial origins of the northern fan were contemporary with the main western delta or significantly predated it. Therefore, this study will examine the morphology of the northern fan and look for geological markers that might help constrain an origin and attempt to identify possible remnants of the northern fan on the crater margin/wall above. This will lead to a more comprehensive understanding of the northern fan and where it fits within the broader Jezero system.

Growing Galaxy Disk - A Study of NGC 3344

Mansi Padave

Abstract

Galaxy growth can be directly linked to star formation. But how exactly does star formation occur in the outer regions of nearby galaxies? My work connects the star formation and interstellar medium in the outer disk of NGC 3344 to find out how the disk grows.

A Spectroscopic Analysis of the Ultraviolet Evolution of K Stars

Tyler Richey-Yowell, Evgenya Shkolnik, Parke Loyd, James Jackman, Adam Schneider, Travis Barman, Victoria Meadows

Abstract

Efforts to discover and characterize habitable zone planets have primarily focused on Sun-like stars and M dwarfs. Yet the intermediate K stars provide an appealing compromise between these two extremes that has been relatively unexplored. Compared to solar-type stars, K stars are more abundant, maintain longer main-sequence lifetimes, and their planets are more suitable to observations based on the mass and radius ratios of the planet to star. While M stars also excel in these regards, they have been observed to have frequent flares with ultraviolet (UV) energies over 100 times greater than anything observed in the recent history of our Sun. Therefore, K stars may provide "super-habitable" environments for exoplanets that are more easily detectable and characterizable. Understanding the UV radiation incident on planets is pivotal in determining the habitability of any planets orbiting these stars, as well as our ability to observe any potential biosignatures in their atmospheres. With this aim, we observed a sample of K stars in the near-UV and far-UV at three representative ages using the Cosmic Origins Spectrograph on the Hubble Space Telescope (HST) to spectroscopically analyze the UV evolution of K stars. Here, we present the first results of this HST program. We will discuss the evolution of both the continuum and line emission from K stars from ages 40 Myr to ~Gyrs, representing key periods in planetary atmospheric formation.

Continuous Habitable Zones: Using Bayesian Methods to Prioritize Characterization of Potentially Habitable Worlds

Austin Ware, Patrick Young

Abstract

The number of potentially habitable planets continues to increase, but we lack the time and resources to characterize them. With ~30 potentially habitable worlds, and that number expected to increase with TESS and future missions, a robust statistical framework for prioritizing characterization of these planets is desirable. Using the ~2 Gy it took life on Earth to make a detectable impact on the atmosphere as a benchmark, we use a Bayesian statistical method to determine the probability that a given radius around a star has been continuously habitable for 2 Gy. We perform this analysis on 9 potentially habitable exoplanets around 9 ~0.5-1.1 M_sun host stars, as well as Venus, Earth, and Mars. Ages for the host stars are generated by the analysis.

Giant Impact origin for the Large Low Shear Velocity provinces

Qian Yuan* Mingming Li, Steven J. Desch, Byeongkwan Ko

Abstract

Halos of Galaxies

Edward Buie II, Evan Scannapieco

Abstract

When we think of galaxies we often imagine a spinning disk with blue lights throughout and a bright center. What we often don't think of is the surrounding cloud of gas, some 20x larger than the central galaxy. While nearly invisible, it is pivotal to how that galaxy evolves.

Investigating the Relationship Between Exoplanet Occurrence & Host Star Metallicity

Adrienne Vescio, Patrick Young

Abstract

We discuss an effort relating to better understanding the conditions that promote planetary formation, investigating the relationship between host star metallicity and exoplanet frequency as it relates to a visible pattern in abundance ratio. In applicable plots comparing the abundance ratios of fundamental system building blocks we observe a separation of the stellar population into two distinct groups, which were selected by eye and individually investigated. We find that between separated populations one will have over twice the occurrence of planet-hosting stars. We anticipate that this finding will promote better understanding of planetary formation and how it depends on the abundances of basic elemental building blocks contained in the protoplanetary disk.

Morphology of the Dust Continuum in Brightest Cluster Galaxies

Anjali Ramesh, Allison Noble, Tracy Webb, Delaney Dunne

Abstract

Studies of high-redshift BCGs have suggested there are significant levels of in-situ star formation but the dominant mode that is driving this star formation is not known. We will explore this by analyzing the morphology in the dust continuum with spatially-resolved ALMA imaging of BCGs over a range of redshifts.

Spectroscopic confirmation of z~7 Lyman-alpha galaxies from LAGER using Keck/LRIS

Santosh Harish, Isak Wold, James E. Rhoads, Sangeeta Malhotra, Weida Hu, Junxian Wang and the LAGER team

Abstract

Lyman-alpha emitters (LAEs) at high-redshifts are powerful probes of cosmic reionization. LAGER (Lyman-Alpha Galaxies in the Epoch of Reionization) survey is the largest survey to find LAEs at z~6.9, covering 24 square-degrees of deep narrow-band imaging from CTIO/DECam. We present results of spectroscopic confirmations using Keck/LRIS. The reductions were carried out using PypeIt, a Python-based data reduction pipeline built for echelle and low-resolution spectrographs. We detect Lyα emission in 16 candidates (12 in COSMOS and 4 in WIDE-12 field) showing a success rate of ~80%. Four of these also have confirmations from Magellan/IMACS. These new confirmations increases the sample of spectroscopically confirmed LAEs at z~7 by a factor >3.

Using the CMB to Construct Maps of Reionization

Darby Kramer, Alexander Van Engelen

Abstract

Maps of the cosmic microwave background (CMB) are collections of data which are heavily sought by cosmologists today. These maps have a wealth of information about the early and modern Universe alike, and it is many cosmologists’ job to extract as much of that information as possible. The anisotropies that exist in its maps are keys to understanding various mechanisms in the Universe that affect the CMB photons. The mechanism of interest in this work is the patchy reionization of the Universe which caused Thomson scattering of the CMB photons. Maps of the effects of reionization can be extracted from temperature and polarization maps of the CMB. Knowledge about the reionization is limited, and analysis of these maps could lead to conclusions about what scales the reionization occurred on and the time frame it occurred within.
