Spectroscopic Orbits of Subsystems in Multiple Stars. VI.
Tokovinin, Andrei
Thirteen spectroscopic orbits of late-type stars are determined from the high-resolution spectra taken with the CHIRON echelle spectrometer at the 1.5 m Cerro Tololo Inter-American Observatory telescope. Most (HIP 14194B, 40523A, 41171A, 51578A, 57572B, 59426A, 62852B, 66438A, 87813B, and 101472A) are inner subsystems in hierarchical multiple star…
The Geology and Astrobiology of McLaughlin Crater, Mars: An Ancient Lacustrine Basin Containing Turbidites, Mudstones, and Serpentinites
Michalski, Joseph R.; Glotch, T. D.; Rogers, A. Deanne +4 more
McLaughlin crater is a 92-km diameter complex crater that formed on Mars 4 billion years ago. The resulting basin was the site of a large ( 3,000 km2), deep ( 500 m), voluminous ( 1,500 km3) Martian lake circa 3.8 Ga. While there is strong evidence that hundreds of lakes have existed on Mars at some point during the same time…
A multiwavelength analysis of a collection of short-duration GRBs observed between 2012 and 2015
Cepa, J.; Troja, E.; Lee, W. H. +71 more
We investigate the prompt emission and the afterglow properties of short-duration gamma-ray burst (sGRB) 130603B and another eight sGRB events during 2012-2015, observed by several multiwavelength facilities including the Gran Canarias Telescope 10.4 m telescope. Prompt emission high energy data of the events were obtained by INTEGRAL-SPI-ACS, Swi…

High-resolution Near-infrared Spectroscopy of HD 100546. IV. Orbiting Companion Disappears on Schedule
Najita, Joan R.; Brittain, Sean D.; Carr, John S.
HD 100546 is a Herbig Ae/Be star surrounded by a disk with a large central region that is cleared of gas and dust (i.e., an inner hole). High-resolution near-infrared spectroscopy reveals a rich emission spectrum of fundamental rovibrational CO emission lines whose time variable properties point to the presence of an orbiting companion within the …
Spectroscopic orbits of nearby stars
Tokovinin, A.; Sperauskas, J.; Deveikis, V.
Aims: We observed stars with variable radial velocities to determine their spectroscopic orbits.
Methods: Velocities are presented of 132 targets taken over a time span reaching 30 years. These were measured with the correlation radial velocity spectrometers (1917 velocities) and the new VUES echelle spectrograph (627 velocities), with a…
The MURALES survey. II. Presentation of MUSE observations of 20 3C low-z radio galaxies and first results
Marconi, A.; Capetti, A.; Gilli, R. +12 more
We present observations of a complete sub-sample of 20 radio galaxies from the Third Cambridge Catalog (3C) with redshift < 0.3 obtained from VLT/MUSE optical integral field spectrograph. These data have been obtained as part of the survey MURALES (a MUse RAdio Loud Emission line Snapshot survey) with the main goal of exploring the active galac…
Radiative and mechanical feedback into the molecular gas in the Large Magellanic Cloud. II. 30 Doradus
Lebouteiller, V.; Madden, S. C.; Galliano, F. +6 more
With an aim of probing the physical conditions and excitation mechanisms of warm molecular gas in individual star-forming regions, we performed Herschel SPIRE Fourier Transform Spectrometer (FTS) observations of 30 Doradus in the Large Magellanic Cloud. In our FTS observations, important far-infrared (FIR) cooling lines in the interstellar medium,…
Stronger Constraints on the Evolution of the M BH-{\sigma }_{* } Relation up to z ∼ 0.6
Canalizo, Gabriela; Sexton, Remington O.; Treister, Ezequiel +4 more
We revisit the possibility of redshift evolution in the M BH-σ * relation with a sample of 22 Seyfert 1 galaxies with black holes (BHs) in the mass range {10}6.3{--}{10}8.3 {M}⊙ and redshift range 0.03 < z < 0.57 with spectra obtained from spatially resolved Keck/Low-resolution Imaging …
Unbiased Cosmological Parameter Estimation from Emission-line Surveys with Interlopers
Schneider, Donald P.; Gebhardt, Karl; Ciardullo, Robin +11 more
The galaxy catalogs generated from low-resolution emission-line surveys often contain both foreground and background interlopers due to line misidentification, which can bias the cosmological parameter estimation. In this paper, we present a method for correcting the interloper bias by using the joint analysis of auto- and cross-power spectra of t…
