Abstract We present the results of a Monte Carlo technique to calculate the absolute magnitudes (H) and slope parameters (G) of ∼240,000 asteroids observed by the Pan-STARRS1 telescope during the first 15 months of its 3-year all-sky survey mission. The system’s exquisite photometry with photometric errors ≲ 0.04 mag , and well-defined filter and photometric system, allowed us to derive accurate H and G even with a limited number of observations and restricted range in phase angles. Our Monte… Expand
Asteroid phase curves from ATLAS dual-band photometry
Abstract Asteroid phase curves are used to derive fundamental physical properties through the determination of the absolute magnitude H. The upcoming visible Legacy Survey of Space and Time (LSST)Expand
An Observational Upper Limit on the Interstellar Number Density of Asteroids and Comets
We derived 90% confidence limits (CL) on the interstellar number density ($\rho_{IS}^{CL}$) of interstellar objects (ISO; comets and asteroids) as a function of the slope of their size-frequencyExpand
The AKARI IRC asteroid flux catalogue: updated diameters and albedos
The AKARI IRC All-sky survey provided more than twenty thousand thermal infrared observations of over five thousand asteroids. Diameters and albedos were obtained by fitting an empirically calibratedExpand
Precise astrometry and diameters of asteroids from occultations – a data set of observations and their interpretation
Occultations of stars by asteroids have been observed since 1961, increasing from a very small number to now over 500 annually. We have created and regularly maintain a growing data-set of more thanExpand
Sizes and albedos of Mars-crossing asteroids from WISE/NEOWISE data
Context. Mars-crossing asteroids (MCs) are a dynamically unstable group between the main belt and the near-Earth populations. Characterising the physical properties of a large sample of MCs can helpExpand
The ATLAS All-Sky Stellar Reference Catalog
The Asteroid Terrestrial-impact Last Alert System (ATLAS) observes most of the sky every night in search of dangerous asteroids. Its data are also used to search for photometric variability, whereExpand
A fast method for quantifying observational selection effects in asteroid surveys
Abstract We present a fast method to calculate an asteroid survey’s ‘bias’ – essentially a correction factor from the observed number of objects to the actual number in the population. The methodExpand
Small and Nearby NEOs Observed by NEOWISE During the First Three Years of Survey: Physical Properties
Automated asteroid detection routines set requirements on the number of detections, signal-to-noise ratio, and the linearity of the expected motion in order to balance completeness, reliability, andExpand
High-fidelity Simulations of the Near-Earth Object Search Performance of the Large Synoptic Survey Telescope
We perform high fidelity simulations of a wide-field telescopic survey searching for Near-Earth Objects (NEO) larger than 140\,m, focusing on the observational and detection model, detectionExpand
Pan-STARRS and PESSTO search for an optical counterpart to the LIGO gravitational-wave source GW150914
We searched for an optical counterpart to the first gravitational-wave source discovered by LIGO (GW150914), using a combination of the Pan-STARRS1 wide-field telescope and the Public ESOExpand


Absolute magnitudes of asteroids and a revision of asteroid albedo estimates from WISE thermal observations
Abstract We obtained estimates of the Johnson V absolute magnitudes ( H ) and slope parameters ( G ) for 583 main-belt and near-Earth asteroids observed at Ondřejov and Table Mountain ObservatoryExpand
Comparison of Positions and Magnitudes of Asteroids Observed in the Sloan Digital Sky Survey with Those Predicted for Known Asteroids
We positionally correlate known asteroids with a sample of ~18,000 asteroids detected by the Sloan Digital Sky Survey (SDSS). We find 2641 unique matches, which represent the largest sample ofExpand
Photometric Calibration of the First 1.5 Years of the Pan-STARRS1 Survey
