The Hot Circumgalactic Medium in Stacked X-Rays: Observations versus Simulations Open
Current cosmological simulations rely on active galactic nucleus (AGN) feedback to quench star formation and match observed stellar mass distributions, but models for AGN feedback are poorly constrained. The circumgalactic medium (CGM) pro…

Cross-correlating the Patchy Screening and Kinetic Sunyaev–Zel’dovich Effects as a New Probe of Reionization Open
The kinetic Sunyaev–Zel’dovich effect (kSZ) and patchy screening effect are two complementary cosmic microwave background (CMB) probes of the reionization era. The kSZ effect is a relatively strong signal, but is difficult to disentangle f…

Improving undergraduate astronomy students’ skills with research literature via accessible summaries: An exploratory case study with Astrobites-based reading assignments Open
Undergraduate physics and astronomy students are expected to engage with scientific literature as they begin their research careers, yet reading comprehension skills are rarely explicitly taught in major courses. We seek to determine the e…

Motivation, demographics, and engagement during COVID-19 in an astrobiology massive open online course Open
Massive open online courses (MOOCs) experienced a resurgence in popularity due to the COVID-19 pandemic. In this work, we studied participants in an astrobiology MOOC offered on Coursera since April 2019. Using a modified version of the Sc…

Development and assessment of a course-based undergraduate research experience for online astronomy majors Open
Course-Based Undergraduate Research Experiences (CUREs) have been shown to provide students with a variety of learning benefits including better conceptual understanding, improved critical thinking and data literacy skills, and increased i…

Distinguishing Active Galactic Nuclei Feedback Models with the Thermal Sunyaev–Zel’dovich Effect Open
Current models of galaxy formation require strong feedback from active galactic nuclei (AGN) to explain the observed lack of star formation in massive galaxies since z ≈ 2, but direct evidence of this energy input is limited. We use the SI…

Distinguishing AGN Feedback Models with the Thermal Sunyaev-Zel'dovich Effect Open
Current models of galaxy formation require strong feedback from active galactic nuclei (AGN) to explain the observed lack of star formation in massive galaxies since z~2 but direct evidence of this energy input is limited. We use the SIMBA…
