On the Image Profiles of Transients in the Palomar Sky Survey
Beatriz Villarroel, Enrique Solano, Geoffrey W. Marcy
The VASCO project has discovered groups of short-lived transients on historical photographic plates that lack conventional explanation. Hambly & Blair (2024) examined nine such tra…
Evidence of Dark Energy Prior to its Discovery
Geoffrey W. Marcy
This is a review and statistical analysis of the evidence supporting the existence of a cosmological constant in the early 1990s, before its discovery made with distant supernovae…
A Search for Transient, Monochromatic Light in a 6-deg Swath along the Galactic Plane
Geoffrey W. Marcy, Nathaniel K. Tellis
We searched the Milky Way Plane along a 6-deg swath for pulses of monochromatic light as faint as 15th mag (V band) using a wide-field telescope equipped with a prism. Pulses with…
A bright triple transient that vanished within 50 minutes
Enrique Solano, Geoffrey W. Marcy, Beatriz Villarroel +5
We report on three optically bright, ~15th mag, point-sources within 10 arcsec of each other that vanished within 1 hour, based on two consecutive exposures at Palomar Observatory…
Astronomical Anomalies: Their Role in the Quest for Extraterrestrial Life
Beatriz Villarroel, Geoffrey W. Marcy
Astronomers occasionally detect an object having unexpected shape, unexplainable photometry, or unprecedented spectra that are inconsistent with our contemporary knowledge of the u…
Masses, Radii, and Orbits of Small Kepler Planets: The Transition from Gaseous to Rocky Planets
Geoffrey W. Marcy, Howard Isaacson, Andrew W. Howard +100
We report on the masses, sizes, and orbits of the planets orbiting 22 Kepler stars. There are 49 planet candidates around these stars, including 42 detected through transits and 7…
