We present 2,241 exoplanet candidates identified with data from the Transiting Exoplanet Survey Satellite (TESS) during its two-year prime mission. list these in TESS Objects of Interest (TOI) Catalog, which includes both new planet found by and previously-known planets recovered observations. describe process used to identify TOIs investigate characteristics candidates, discuss some notable discoveries. The TOI Catalog an unprecedented number small around nearby bright stars, are...
We present and make publicly available the first data release (DR1) of Keck Observatory Database Ionized Absorption toward Quasars (KODIAQ) survey. The KODIAQ survey is aimed at studying galactic circumgalactic gas in absorption high-redshift, with a focus on highly-ionized traced by OVI, using HIRES spectrograph Keck-I telescope. DR1 consists fully-reduced sample 170 quasars 0.29 < z_em 5.29 observed high resolution (36,000 <= R 103,000) between 2004 2012. contains 247 spectra continuum...
Objective We investigated the 5-year postsurgical developmental trajectory of working memory (WM) in children with medulloblastoma using parent and performance-based measures. Method This study included 167 patients treated for medulloblastoma. Serial assessments WM occurred at predetermined time points 5 years. Results There was a subtle, statistically significant increase parental concern about WM, coupled decrease age-standardized scores on However, whole-group mean both measures remained...
For all active instruments, the Keck Observatory Archive (KOA) now ingests raw data from Telescopes within 1 minute of acquisition, quick-look reduced 5 minutes creation, and science ready for four instruments as they are created by their automated pipelines. On August 1, 2023, KOA released Observers Data Access Portal (ODAP), which enables observers at telescope collaborators anywhere in world to securely monitor download science, calibration, ingested into archive. The portal is built...

The Infrared Processing and Analysis Center (IPAC) the W. M. Keck Observatory (WMKO) operate an archive for Observatory. At end of 2013, KOA completed ingestion data from all eight active observatory instruments. will continue to ingest newly obtained observations, at anticipated volume 4 TB per year. are transmitted electronically WMKO IPAC storage curation. Access is governed by a use policy, approximately two-thirds in public.
The Keck Observatory Archive (KOA) currently serves ~ 42 TB of data spanning over 20 years from all ten past and current facility instruments at Keck. Although most the available are in raw form, for four (HIRES, NIRC2, OSIRIS, LWS), quick-look, browse products generated by automated pipelines also offered to facilitate assessment scientific content quality data. KOA underwrote update MAKEE package support reduction CCD upgrade HIRES, developed scripts NIRC2 existing OSIRIS LWS packages. We...
A collaboration between the W. M. Keck Observatory (WMKO) in Hawaii and NASA Exoplanet Science Institute (NExScI) California, Archive (KOA) was commissioned 2004 to archive observing data from WMKO, which operates two classically scheduled 10 m ground-based telescopes. The is not suitable for direct ingestion into since metadata contained original FITS headers lack information necessary proper archiving. Coupled with different standards among instrument builders heterogeneous nature of...
Trigonometric parallaxes and proper motions are presented for 32 late-type stars observed photographically with the Leander McCormick 67 cm refractor. Eighteen of have no previously published parallaxes. Twenty one K M dwarfs identified by Vyssotsky his collaborators. The list includes several x-ray luminous dwarfs, a rapidly rotating spotted flare star, two astrometric binaries.
The W. M. Keck Observatory is welcoming a new era where data reduction and archiving are tightly integrated into our observing model, under the auspices of Observatory's Data Services Initiative (DSI) project. While previously Archive (KOA) archived minimally processed, raw science day after observing, transitioning to model in which it archives both frames reduced near real-time. These will be made available observers collaborators immediately upon ingestion through dedicated interface that...

The Keck Observatory Archive (KOA) (https://koa.ipac.caltech.edu) curates all observations acquired at the W. M. (WMKO) since it began operations in 1994, including data from eight active instruments and two decommissioned instruments. archive is a collaboration between WMKO NASA Exoplanet Science Institute (NExScI). Since its inception 2004, science information system used KOA has adopted an architectural approach that emphasizes software re-use adaptability. This paper describes how...
Thoth is a free desktop/laptop software application with friendly graphical user interface that facilitates routine data-visualization and statistical-calculation tasks for astronomy astrophysical research (and other fields where numbers are visualized). This has been upgraded many significant improvements new capabilities. The major upgrades consist of: (1) six graph types, including 3D stacked-bar charts surface plots, made by the Orson Charts library; (2) saving loading of settings; (3)...
