The MUSE Hubble Ultra Deep Field Survey. II. Spectroscopic redshifts and comparisons to color selections of high-redshift galaxies
Inami, H.; Kollatschny, W.; Richard, J. +22 more
We have conducted a two-layered spectroscopic survey (1' × 1' ultra deep and 3' × 3' deep regions) in the Hubble Ultra Deep Field (HUDF) with the Multi Unit Spectroscopic Explorer (MUSE). The combination of a large field of view, high sensitivity, and wide wavelength coverage provides an order of magnitude improvement in spectroscopically confirme…
Magnetospheric Science Objectives of the Juno Mission
Hansen, C. J.; Kurth, W. S.; McComas, D. J. +18 more
In July 2016, NASA's Juno mission becomes the first spacecraft to enter polar orbit of Jupiter and venture deep into unexplored polar territories of the magnetosphere. Focusing on these polar regions, we review current understanding of the structure and dynamics of the magnetosphere and summarize the outstanding issues. The Juno mission profile in…
The Constant Average Relationship between Dust-obscured Star Formation and Stellar Mass from z = 0 to z = 2.5
Casey, Caitlin M.; Cybulski, Ryan; Yun, Min S. +3 more
The total star formation budget of galaxies consists of the sum of the unobscured star formation, as observed in the rest-frame ultraviolet (UV), together with the obscured component that is absorbed and re-radiated by dust grains in the infrared. We explore how the fraction of obscured star formation depends on stellar mass for mass-complete samp…
FRB 121102 Is Coincident with a Star-forming Region in Its Host Galaxy
Ransom, S. M.; Chatterjee, S.; Cordes, J. M. +16 more
We present optical, near-infrared, and mid-infrared imaging of the host galaxy of FRB 121102 with the Gemini North telescope, the Hubble Space Telescope, and the Spitzer Space Telescope. The FRB 121102 host galaxy is resolved, revealing a bright star-forming region located in the outskirts of the irregular, low-metallicity dwarf galaxy. The star-f…
The binarity of the local white dwarf population
Gänsicke, B. T.; Toonen, S.; Hollands, M. +1 more
Context. As endpoints of stellar evolution, white dwarfs (WDs) are powerful tools to study the evolutionary history of the Galaxy. In particular, the multiplicity of WDs contains information regarding the formation and evolution of binary systems.
Aims: Can we understand the multiplicity of the local WD sample from a theoretical point of view…
The extragalactic background light revisited and the cosmic photon-photon opacity
Franceschini, Alberto; Rodighiero, Giulia
Context. In addition to its relevant astrophysical and cosmological significance, the extragalactic background light (EBL) is a fundamental source of opacity for cosmic high energy photons, as well as a limitation for the propagation of high-energy particles in the Universe.
Aims: We review our previously published determinations of the EBL p…
The impact of clustering and angular resolution on far-infrared and millimeter continuum observations
Daddi, Emanuele; Béthermin, Matthieu; Wu, Hao-Yi +7 more
Follow-up observations at high-angular resolution of bright submillimeter galaxies selected from deep extragalactic surveys have shown that the single-dish sources are comprised of a blend of several galaxies. Consequently, number counts derived from low- and high-angular-resolution observations are in tension. This demonstrates the importance of …
The Open Flux Problem
Liu, Y.; Arge, C. N.; Henney, C. J. +9 more
The heliospheric magnetic field is of pivotal importance in solar and space physics. The field is rooted in the Sun’s photosphere, where it has been observed for many years. Global maps of the solar magnetic field based on full-disk magnetograms are commonly used as boundary conditions for coronal and solar wind models. Two primary observational c…
The VLA-COSMOS 3 GHz Large Project: Multiwavelength counterparts and the composition of the faint radio population
Bondi, M.; Berta, S.; Ilbert, O. +18 more
We study the composition of the faint radio population selected from the Karl G. Jansky Very Large Array Cosmic Evolution Survey (VLA-COSMOS) 3 GHz Large Project, which is a radio continuum survey performed at 10 cm wavelength. The survey covers a 2.6 square degree area with a mean rms of 2.3 µJy/beam, cataloging 10 830 sources above 5σ, and…
New constraints on Saturn's interior from Cassini astrometric data
Thuillot, William; Pascu, Dan; Guillot, Tristan +15 more
Using astrometric observations spanning more than a century and including a large set of Cassini data, we determine Saturn's tidal parameters through their current effects on the orbits of the eight main and four coorbital Moons. We have used the latter to make the first determination of Saturn's Love number from observations, k2=0.390 …
