Coherent radio bursts from known M-dwarf planet-host YZ Ceti
Pineda, J. Sebastian; Villadsen, Jackie
Observing magnetic star-planet interactions (SPIs) offers promise for determining the magnetic fields of exoplanets. Models of sub-Alfvénic SPIs predict that terrestrial planets in close-in orbits around M dwarfs can induce detectable stellar radio emission, manifesting as bursts of strongly polarized coherent radiation observable at specific plan…
JWST/NIRSpec Measurements of Extremely Low Metallicities in High Equivalent Width Lyα Emitters
Feltre, Anna; Bacon, Roland; Inami, Hanae +19 more
Deep Very Large Telescope/MUSE optical integral field spectroscopy has recently revealed an abundant population of ultra-faint galaxies (M UV ≈ -15; 0.01 L ⋆) at z = 2.9-6.7 due to their strong Lyα emission with no detectable continuum. The implied Lyα equivalent widths can be in excess of 100-200 Å, challenging existing mode…
Gaia Data Release 3. Ellipsoidal variables with possible black hole or neutron star secondaries
Mazeh, T.; Audard, M.; Rimoldini, L. +10 more
As part of Gaia Data Release 3, a large number of ellipsoidal variables were identified with supervised classification. The periodic variability of these ellipsoidals is presumably induced by tidal interaction with a companion in a close binary system. We present 6306 short-period probable ellipsoidal variables with relatively large-amplitude Gaia…
The Fifth Catalogue of Nearby Stars (CNS5)
Reffert, Sabine; Golovin, Alex; Vani, Akash +3 more
Context. We present the compilation of the Fifth Catalogue of Nearby Stars (CNS5), based on astrometric and photometric data from Gaia EDR3 and HIPPARCOS and supplemented with parallaxes from ground-based astrometric surveys carried out in the infrared.
Aims: The aim of the CNS5 is to provide the most complete sample of objects in the solar n…
HYPerluminous quasars at the Epoch of ReionizatION (HYPERION): A new regime for the X-ray nuclear properties of the first quasars
Maiolino, R.; Fiore, F.; Done, C. +40 more
The existence of luminous quasars (QSOs) at the epoch of reionization (EoR; i.e., z > 6) powered by well-grown supermassive black holes (SMBHs) with masses ≳109 M⊙ challenges models of early SMBH formation and growth. To shed light on the nature of these sources, we started a multiwavelength program based on a sample of 18…
PHANGS-JWST First Results: Duration of the Early Phase of Massive Star Formation in NGC 628
Kruijssen, J. M. Diederik; Longmore, Steven N.; Leroy, Adam K. +33 more
The earliest stages of star formation, when young stars are still deeply embedded in their natal clouds, represent a critical phase in the matter cycle between gas clouds and young stellar regions. Until now, the high-resolution infrared observations required for characterizing this heavily obscured phase (during which massive stars have formed, b…
RC100: Rotation Curves of 100 Massive Star-forming Galaxies at z = 0.6-2.5 Reveal Little Dark Matter on Galactic Scales
Lutz, D.; Wuyts, S.; Förster Schreiber, N. M. +19 more
We analyze Hα or CO rotation curves extending out to several galaxy effective radii for 100 massive, large, star-forming disk galaxies (SFGs) across the peak of cosmic galaxy star formation (z ~ 0.6-2.5), more than doubling the previous sample presented by Genzel et al. and Price et al. The observations were taken with SINFONI and KMOS integral-fi…
An empirical study of dust properties at the earliest epochs
Maiolino, Roberto; Jones, Gareth C.; Smit, Renske +2 more
We present an empirical analysis of the properties of dust-continuum emission in a sample of 17 galaxies in the early Universe (4 < z < 8) with well-sampled far-infrared spectral energy distributions (SEDs) compiled from the literature. We place our results into context by self-consistently comparing to samples of nearby star-forming galaxie…
Hunting for Neighboring Open Clusters with Gaia DR3: 101 New Open Clusters within 500 pc
Chen, Li; Zhong, Jing; Qin, Songmei +1 more
We systematically searched for open clusters in the solar neighborhood within 500 pc using the pyUPMASK and HDBSCAN clustering algorithms based on Gaia DR3. Taking into consideration that the physical size for most open clusters is less than 50 pc, we adopted a slicing approach for different distance shells and identified 324 neighboring open clus…
Extending optical flare models to the UV: results from comparing of TESS and GALEX flare observations for M Dwarfs
Loyd, R. O. Parke; Jackman, James A. G.; Richey-Yowell, Tyler +3 more
The ultraviolet (UV) emission of stellar flares may have a pivotal role in the habitability of rocky exoplanets around low-mass stars. Previous studies have used white-light observations to calibrate empirical models which describe the optical and UV flare emission. However, the accuracy of the UV predictions of models has previously not been test…
