Photometry as a Proxy for Stellar Activity in Radial Velocity Analyses [PDF]
Astronomical Journal, 2020 Stellar activity remains a limiting factor in measuring precise planet parameters from radial velocity spectroscopy, not least in the search for Earth-mass planets orbiting in the habitable zones of Sun-like stars.

Depth-resolved fiber photometry with a single tapered optical fiber implant
Nature Methods, 2019 Fiber photometry is increasingly utilized to monitor fluorescent sensors of neural activity in the brain. However, most implementations are based on flat-cleaved optical fibers that can only interface with shallow tissue volumes adjacent to the fiber. We

HIGH-CADENCE, HIGH-CONTRAST IMAGING FOR EXOPLANET MAPPING: OBSERVATIONS OF THE HR 8799 PLANETS WITH VLT/SPHERE SATELLITE-SPOT-CORRECTED RELATIVE PHOTOMETRY [PDF]
Astrophysical Journal, 2016 Time-resolved photometry is an important new probe of the physics of condensate clouds in extrasolar planets and brown dwarfs. Extreme adaptive optics systems can directly image planets, but precise brightness measurements are challenging. We present VLT/

INTERPRETING FLUX FROM BROADBAND PHOTOMETRY [PDF]
, 2016 We discuss the transformation of observed photometry into flux for the creation of spectral energy distributions (SED) and the computation of bolometric luminosities. We do this in the context of supernova studies, particularly as observed with the Swift

Chemogenetic Control of Striatal Astrocytes Improves Parkinsonian Motor Deficits in Mice. [PDF]
GliaMain Points Dopamine depletion reduces locomotion‐induced calcium activity in dorsal striatal astrocytes. Chemogenetic activation facilitates astrocyte locomotion responses and improves motor behavior in dopamine lesioned animals. ABSTRACT Parkinson's disease (PD) is characterized by the degeneration of dopaminergic nigrostriatal inputs, which causes ...
