Hot explosions in the cool atmosphere of the Sun
Peter, H.; Golub, L.; Curdt, W. +20 more
The solar atmosphere was traditionally represented with a simple one-dimensional model. Over the past few decades, this paradigm shifted for the chromosphere and corona that constitute the outer atmosphere, which is now considered a dynamic structured envelope. Recent observations by the Interface Region Imaging Spectrograph (IRIS) reveal that it …
Global climate modeling of the Martian water cycle with improved microphysics and radiatively active water ice clouds
Forget, F.; Montmessin, F.; Millour, E. +4 more
Water ice clouds play a key role in the radiative transfer of the Martian atmosphere, impacting its thermal structure, its circulation, and, in turn, the water cycle. Recent studies including the radiative effects of clouds in global climate models (GCMs) have found that the corresponding feedbacks amplify the model defaults. In particular, it pre…
ALMA Imaging of Gas and Dust in a Galaxy Protocluster at Redshift 5.3: [C II] Emission in "Typical" Galaxies and Dusty Starbursts ≈1 Billion Years after the Big Bang
Schinnerer, Eva; Scoville, Nicholas Z.; Carilli, Christopher L. +8 more
We report interferometric imaging of [C II](2 P 3/2→2 P 1/2) and OH(2Π1/2 J = 3/2→1/2) emission toward the center of the galaxy protocluster associated with the z = 5.3 submillimeter galaxy (SMG) AzTEC-3, using the Atacama Large (sub)Millimeter Array (ALMA). We detect strong [C II],…
Tracing the cosmic growth of supermassive black holes to z ∼ 3 with Herschel
Berta, S.; Magnelli, B.; Lutz, D. +23 more
We study a sample of Herschel selected galaxies within the Great Observatories Origins Deep Survey-South and the Cosmic Evolution Survey fields in the framework of the Photodetector Array Camera and Spectrometer (PACS) Evolutionary Probe project. Starting from the rich multiwavelength photometric data sets available in both fields, we perform a br…
From Binaries to Multiples. I. Data on F and G Dwarfs within 67 pc of the Sun
Tokovinin, Andrei
Data on the multiplicity of F- and G-type dwarf stars within 67 pc of the Sun are presented. This distance-limited sample based on the Hipparcos catalog contains 4847 primary stars (targets) with 0.5 < V - IC < 0.8 and is >90% complete. There are 2196 known stellar pairs; some of them belong to 361 hierarchical systems from tri…
Hubble Space Telescope Near-IR Transmission Spectroscopy of the Super-Earth HD 97658b
Fortney, Jonathan J.; Knutson, Heather A.; Howard, Andrew W. +7 more
Recent results from the Kepler mission indicate that super-Earths (planets with masses between 1-10 times that of the Earth) are the most common kind of planet around nearby Sun-like stars. These planets have no direct solar system analogue, and are currently one of the least well-understood classes of extrasolar planets. Many super-Earths have av…
The Lyα Properties of Faint Galaxies at z ~ 2-3 with Systemic Redshifts and Velocity Dispersions from Keck-MOSFIRE
Pettini, Max; Erb, Dawn K.; Shapley, Alice E. +13 more
We study the Lyα profiles of 36 spectroscopically detected Lyα-emitters (LAEs) at z ~ 2-3, using Keck MOSFIRE to measure systemic redshifts and velocity dispersions from rest-frame optical nebular emission lines. The sample has a median optical magnitude R}=26.0, and ranges from R}≃ 23 to R}\gt27, corresponding to rest-frame UV absolute magnitudes…
Probing for Exoplanets Hiding in Dusty Debris Disks: Disk Imaging, Characterization, and Exploration with HST/STIS Multi-roll Coronagraphy
Henning, Thomas; Stark, Christopher C.; Weinberger, Alycia J. +16 more
Spatially resolved scattered-light images of circumstellar debris in exoplanetary systems constrain the physical properties and orbits of the dust particles in these systems. They also inform on co-orbiting (but unseen) planets, the systemic architectures, and forces perturbing the starlight-scattering circumstellar material. Using Hubble Space Te…
Direct Measurements of Dust Attenuation in z ~ 1.5 Star-forming Galaxies from 3D-HST: Implications for Dust Geometry and Star Formation Rates
van Dokkum, Pieter G.; Franx, Marijn; Conroy, Charlie +11 more
The nature of dust in distant galaxies is not well understood, and until recently few direct dust measurements have been possible. We investigate dust in distant star-forming galaxies using near-infrared grism spectra of the 3D-HST survey combined with archival multi-wavelength photometry. These data allow us to make a direct comparison between du…
The ATLAS3D Project - XXVIII. Dynamically driven star formation suppression in early-type galaxies
Krajnović, Davor; Emsellem, Eric; Sarzi, Marc +22 more
We present measurements of the star formation rate (SFR) in the early-type galaxies (ETGs) of the ATLAS3D sample, based on Wide-field Infrared Survey Explorer (WISE) 22 µm and Galaxy Evolution Explorer far-ultraviolet emission. We combine these with gas masses estimated from 12CO and H I data in order to investigate the…
