Towards windproofing LIGO: Reducing the effect of wind-driven floor tilt by using rotation sensors in active seismic isolation

Posted by klaurent MIT

Kavli Affiliate: Richard Mittleman | First 5 Authors: Michael P. Ross, Krishna Venkateswara, Conor Mow-Lowry, Sam Cooper, Jim Warner | Summary: Modern gravitational-wave observatories require robust low-frequency active seismic isolation in order to keep the interferometer at its ideal operating conditions. Seismometers are used to measure both the motion of the ground and isolated platform. […]

Absorption line abundances in the SMC-like galaxy UGC 5282: evidence for ISM dilution from inflows on kiloparsec scales

Posted by klaurent Chicago

Kavli Affiliate: Donald G. York | First 5 Authors: David V. Bowen, Todd M. Tripp, Edward B. Jenkins, Max Pettini, Doron Chelouche | Summary: We present an HST Cosmic Origins Spectrograph (COS) spectrum of the QSO SDSS J095109.12+330745.8 ($z_{em} = 0.645$) whose sightline passes through the SMC-like dwarf galaxy UGC 5282 ($M_B = -16.0$, $cz […]

Systematic Phase Curve Study of Known Transiting Systems from Year 1 of the TESS Mission

Posted by klaurent MIT

Kavli Affiliate: Robert F. Goeke | First 5 Authors: Ian Wong, Avi Shporer, Tansu Daylan, Björn Benneke, Tara Fetherolf | Summary: We present a systematic phase curve analysis of known transiting systems observed by the Transiting Exoplanet Survey Satellite (TESS) during year one of the primary mission. Using theoretical predictions for the amplitude of the […]
