Extending Gaia DR2 with HST narrow-field astrometry. II. Refining the method on WISE J163940.83-684738.6
L. R. Bedin, C. Fontanive
In the second paper of this series we perfected our method of linking high precision Hubble Space Telescope astrometry to the high-accuracy Gaia DR2 absolute reference system to ov…
Extending Gaia DR2 with HST narrow-field astrometry: the WISE J154151.65-225024.9 test case
L. R. Bedin, C. Fontanive
One field containing WISE J154151.65-225024.9 was observed by Hubble Space Telescope at three different epochs taken in ~5 yrs. We measured positions of sources in all images and s…
Type Ia supernova diversity: Standardizing the candles
T. M. Davis, J. B. James, B. P. Schmidt +1
Future use of type Ia supernovae for cosmology aims not only to determine the equation of state of dark energy, but also to constrain possible variations in its value. To achieve t…
Around the Clock Observations of the Q0957+561 A,B Gravitationally Lensed Quasar II: Results for the second observing season
Wesley N. Colley, Rudolph E. Schild, Cristina Abajas +35
We report on an observing campaign in March 2001 to monitor the brightness of the later arriving Q0957+561 B image in order to compare with the previously published brightness obse…
