Teaching Astronomy with an Inquiry Activity on Stellar Populations
Marc Rafelski, Michael Foley, Genevieve J. Graves +4
We describe a new inquiry design aimed at teaching advanced high-school to senior college students the basics of stellar populations. The inquiry is designed to have students come…
On-sky single-mode fiber coupling measurements at the Large Binocular Telescope
Andrew Bechter, Jonathan Crass, Ryan Ketterer +12
The demonstration of efficient single-mode fiber (SMF) coupling is a key requirement for the development of a compact, ultra-precise radial velocity (RV) spectrograph. iLocater is…
The Landscape of Undergraduate Astronomy and Astrophysics Degree Requirements
Kate Follette, Carl Ferkinhoff, Michael Foley +5
In this document we summarize the results of a survey of undergraduate degree-granting programs conducted by the 2024-2025 American Astronomical Society Education Committee's Subco…
Performance of photosensors in a high-rate environment for gas Cherenkov detectors
Chao Peng, Junqi Xie, Sylvester Joosten +10
The solenoidal large intensity device (SoLID) at Jefferson Lab will push the boundaries of luminosity for a large-acceptance detector, which necessitates the use of a light-gas thr…
Revised Uncertainties in Big Bang Nucleosynthesis
Michael Foley, Nishanth Sasankan, Motohiko Kusakabe +1
Big Bang Nucleosynthesis (BBN) explores the first few minutes of nuclei formation after the Big Bang. We present updates that result in new constraints at the 2Ï level for the abu…
CAE: Character-Level Autoencoder for Non-Semantic Relational Data Grouping
Veera V S Bhargav Nunna, Shinae Kang, Zheyuan Zhou +3
Enterprise relational databases increasingly contain vast amounts of non-semantic data - IP addresses, product identifiers, encoded keys, and timestamps - that challenge traditiona…
Advances in the Large Area Picosecond Photo-Detector (LAPPD): 8" x 8" MCP-PMT with Capacitively Coupled Readout
Shawn Shin, Melvin Aviles, Stephen Clarke +8
We present advances made in the Large Area Picosecond Photodetector (LAPPD), an 8" 8" microchannel plate photomultiplier tube (MCP-PMT), since pilot production was initiat…
The Radcliffe Wave is Oscillating
Ralf Konietzka, Alyssa A. Goodman, Catherine Zucker +6
Our Sun lies within 300 pc of the 2.7-kpc-long sinusoidal chain of dense gas clouds known as the Radcliffe Wave. The structure's wave-like shape was discovered using 3D dust mappin…
Star formation near the Sun is driven by expansion of the Local Bubble
Catherine Zucker, Alyssa A. Goodman, João Alves +8
For decades we have known that the Sun lies within the Local Bubble, a cavity of low-density, high-temperature plasma surrounded by a shell of cold, neutral gas and dust. However,…
Conflict and Convention in Dynamic Networks
Michael Foley, Patrick Forber, Rory Smead +1
An important way to resolve games of conflict (snowdrift, hawk-dove, chicken) involves adopting a convention: a correlated equilibrium that avoids any conflict between aggressive s…
Avoiding the bullies: The resilience of cooperation among unequals
Michael Foley, Rory Smead, Patrick Forber +1
Can egalitarian norms or conventions survive the presence of dominant individuals who are ensured of victory in conflicts? We investigate the interaction of power asymmetry and par…
Evidence for Radial Expansion at the Core of the Orion Complex with Gaia EDR3
Cameren Swiggum, Elena D'Onghia, João Alves +6
We present a phase-space study of two stellar groups located at the core of the Orion complex: Briceño-1 and Orion Belt Population-near (OBP-near). We identify the groups with the…
