Measuring the linear gain performance for the OrcaQuest CMOS imaging sensor
Zain Azama, Aditya Khandelwal, Ryan Dungee +3
The OrcaQuest CMOS sensor by Hamamatsu Photonics has been found to exhibit a non-linear gain curve at low exposure times. This effect is characterized through the various exposure…
Wavefront Profiling via correlation of GLAO open loop telemetry
Eden A. McEwen, Ryan Dungee, Mark Chun +3
Adaptive Optics (AO) used in ground based observatories can be strengthened in both design and algorithms by a more detailed understanding of the atmosphere they seek to correct. N…
Beyond CCDs: Characterization of sCMOS detectors for optical astronomy
Aditya Khandelwal, Sarik Jeram, Ryan Dungee +7
Modern scientific complementary metal-oxide semiconductor (sCMOS) detectors provide a highly competitive alternative to charge-coupled devices (CCDs), the latter of which have hist…
The TIME Table: Rotation and Ages of Cool Exoplanet Host Stars
Eric Gaidos, Zachary Claytor, Ryan Dungee +2
Age is a stellar parameter that is both fundamental and difficult to determine. Among middle-aged M dwarfs, the most prolific hosts of close-in and detectable exoplanets, gyrochron…
A 4 Gyr M-dwarf Gyrochrone from CFHT/MegaPrime Monitoring of the Open Cluster M67
Ryan Dungee, Jennifer van Saders, Eric Gaidos +5
We present stellar rotation periods for late K- and early M-dwarf members of the 4 Gyr old open cluster M67 as calibrators for gyrochronology and tests of stellar spin-down models.…
Worry No More, The Hubble Tension is Relieved: A Truly Direct Measurement of the Hubble Constant from Mooniversal Expansion
Gagandeep S. Anand, Zachary R. Claytor, Ryan Dungee
Using sedimentary and eclipse-based measurements of the lunar recession velocity, we derive a new local-Universe measurement of the Hubble constant () from the recession rate…
