MOSEL survey: extremely weak outflows in EoR analogues at z = 3-4
Kewley, Lisa J.; Harshan, Anishya; Kacprzak, Glenn G. +7 more
This paper presents deep K-band spectroscopic observations of galaxies at z = 3 - 4 with composite photometric rest-frame H Β+[O III] 5007 equivalent widths (EW0) > 600 Å, comparable to the EW of galaxies observed during the epoch of reionization (EoR, z > 6). The typical spectroscopic [O III] 5007 EW0 and stellar mass …
Three Warm Jupiters around Solar-analog Stars Detected with TESS
Trifonov, Trifon; Henning, Thomas; Triaud, Amaury H. M. J. +32 more
We report the discovery and characterization of three giant exoplanets orbiting solar-analog stars, detected by the TESS space mission and confirmed through ground-based photometry and radial velocity measurements taken at La Silla observatory with FEROS. TOI-2373 b is a warm Jupiter orbiting its host star every ~13.3 days, and is one of the most …
Hint of an exocomet transit in the CHEOPS light curve of HD 172555
Alonso, R.; Deleuil, M.; Erikson, A. +72 more
HD 172555 is a young (~20 Myr) A7V star surrounded by a 10 au wide debris disk suspected to be replenished partly by collisions between large planetesimals. Small evaporating transiting bodies, that is exocomets, have also been detected in this system by spectroscopy. After β Pictoris, this is another example of a system possibly witnessing a phas…
In-flight radiometric calibration of the Metis Visible Light channel using stars and comparison with STEREO-A/COR2 data
Heinzel, P.; Sasso, C.; Romoli, M. +45 more
Context. We present the results for the in-flight radiometric calibration performed for the Visible Light (VL) channel of the Metis coronagraph on board Solar Orbiter.
Aims: The radiometric calibration is a fundamental step in building the official pipeline of the instrument, devoted to producing the calibrated data in physical units (L2 data…
ALMA Measurement of 10 kpc Scale Lensing-power Spectra toward the Lensed Quasar MG J0414+0534
Matsushita, Satoki; Minezaki, Takeo; Nakanishi, Kouichiro +1 more
The lensing power spectra for gravitational potential, astrometric shift, and convergence perturbations are powerful probes to investigate dark matter structures on small scales. We report the first lower and upper bounds of these lensing power spectra on angular scale ~1″ toward the anomalous quadruply lensed quasar MG J0414+0534 at a redshift z …
LISC Catalog of Star Clusters. II. High Galactic Latitude Open Clusters in Gaia EDR3
Li, Zhongmu; Mao, Caiyan
It is well known that there are few open clusters (OCs) in the high-latitude region of the Milky Way galaxy, because most star formation takes place in the thin disk. It is therefore crucial to look for high Galactic latitude OCs, in order to understand OCs and the Galactic parts outside the plane well. This work looks for high Galactic latitude O…
Observing the onset of the accretion wake in Vela X-1
Santangelo, A.; Grinberg, V.; Kretschmar, P. +7 more
High-mass X-ray binaries (HMXBs) offer a unique opportunity to investigate accretion onto compact objects and the wind structure in massive stars. A key source for such studies is the bright neutron star HMXB Vela X-1 whose convenient physical and orbital parameters facilitate analyses and in particular enable studies of the wind structure in HMXB…
Clusters, clouds, and correlations: relating young clusters to giant molecular clouds in M33 and M31
Bell, Eric F.; Skillman, Evan D.; Williams, Benjamin F. +11 more
We use young clusters and giant molecular clouds (GMCs) in the galaxies M33 and M31 to constrain temporal and spatial scales in the star formation process. In M33, we compare the Panchromatic Hubble Andromeda Treasury: Triangulum Extended Region (PHATTER) catalogue of 1214 clusters with ages measured via colour-magnitude diagram (CMD) fitting to 4…
Implications of Different Solar Photospheric Flux-transport Models for Global Coronal and Heliospheric Modeling
Cheung, Mark C. M.; DeRosa, Marc L.; Barnes, Graham +3 more
The concept of surface-flux transport (SFT) is commonly used in evolving models of the large-scale solar surface magnetic field. These photospheric models are used to determine the large-scale structure of the overlying coronal magnetic field, as well as to make predictions about the fields and flows that structure the solar wind. We compare predi…
First Results from the JWST Early Release Science Program Q3D: Benchmark Comparison of Optical and Mid-infrared Tracers of a Dusty, Ionized Red Quasar Wind at z = 0.435
Shen, Lu; Johnson, Sean D.; Lützgendorf, Nora +27 more
The [O III] 5007 Å emission line is the most common tracer of warm, ionized outflows in active galactic nuclei across cosmic time. JWST newly allows us to use mid-IR spectral features at both high spatial and spectral resolution to probe these same winds. Here we present a comparison of ground-based, seeing-limited [O III] and space-based, diffrac…
