Journal Article
Chávez Ortiz, Ó. A., Leung, G. C. K., Finkelstein, S. L., Davis, D., Sutherland, R. S., Nicholls, D. C., Stephenson, M., Mentuch Cooper, E., Bagley, M., Gebhardt, K., House, L. R., Liu, C., Ciardullo, R., Gronwall, C., Hill, G. J., Farrow, D., & Schneider, D. P. (2024). The Lyα Dependence on Nebular Properties from the HETDEX and MOSDEF Surveys. The Astrophysical journal, 977(1), Article 107. https://doi.org/10.3847/1538-4357/ad7a00

Investigating the impact of galaxy properties on emergent Lyα emission is crucial for reionization studies, given the sensitivity of Lyα to neutral hydrogen. This study presents an analysis of the physical characteristics of 155 star-forming galaxies... Read More about The Lyα Dependence on Nebular Properties from the HETDEX and MOSDEF Surveys.

Participatory Science and Machine Learning Applied to Millions of Sources in the Hobby-Eberly Telescope Dark Energy Experiment (2024)
Journal Article
House, L. R., Gebhardt, K., Finkelstein, K., Mentuch Cooper, E., Davis, D., Farrow, D., & Schneider, D. P. (2024). Participatory Science and Machine Learning Applied to Millions of Sources in the Hobby-Eberly Telescope Dark Energy Experiment. The Astrophysical journal, 975(2), Article 172. https://doi.org/10.3847/1538-4357/ad782c

We are merging a large participatory science effort with machine learning to enhance the Hobby–Eberly Telescope Dark Energy Experiment (HETDEX). Our overall goal is to remove false positives, allowing us to use lower signal-to-noise data and sources...

Do galaxy mergers prefer under-dense environments? (2024)
Journal Article
Sureshkumar, U., Durkalec, A., Pollo, A., Pearson, W., Farrow, D., Narayanan, A., Loveday, J., Taylor, E., & Suelves, L. (2024). Do galaxy mergers prefer under-dense environments?. Astronomy and Astrophysics, 686, Article A40. https://doi.org/10.1051/0004-6361/202347705

Context. Galaxy mergers play a crucial role in galaxy evolution. However, the correlation between mergers and the local environment of galaxies is not fully understood.
Aims. We aim to address the question of whether galaxy mergers prefer denser or... Read More about Do galaxy mergers prefer under-dense environments?.

Journal Article
Weiss, L. H., Davis, D., Gebhardt, K., Gazagnes, S., Mirza Khanlari, M., Mentuch Cooper, E., Chisholm, J., Berg, D., Bowman, W. P., Byrohl, C., Ciardullo, R., Fabricius, M., Farrow, D., Gronwall, C., Hill, G. J., House, L. R., Jeong, D., Khoraminezhad, H., Kollatschny, W., Komatsu, E., …Zeimann, G. R. (2024). Absorption Troughs of Lyα Emitters in HETDEX. The Astrophysical journal, 962(2), Article 102. https://doi.org/10.3847/1538-4357/ad1b51

The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is designed to detect and measure the redshifts of more than 1 million Lyα emitting galaxies (LAEs) 1.88 < z < 3.52. In addition to its cosmological measurements, these data enable studies of... Read More about Absorption Troughs of Lyα Emitters in HETDEX.
