Kinematics and Star Formation in the Hub–Filament System G6.55-0.1
Wyrowski, Friedrich; Güsten, Rolf; Ishwara-Chandra, C. H. +2 more
Hub–filament systems (HFSs) being the potential sites of formation of star clusters and high-mass stars, provide a testbed for the current theories that attempt to explain star formation globally. It is thus important to study a large number of HFSs using both intensity and velocity information to constrain these objects better observationally. He…
A Deep Redshift Survey of the Perseus Cluster (A426): Spatial Distribution and Kinematics of Galaxies
Park, Byeong-Gon; Hwang, Narae; Hwang, Ho Seong +3 more
We study the global kinematics of the Perseus galaxy cluster (A426) at redshift z = 0.017 using a large sample of galaxies from our new MMT/Hectospec spectroscopic observation for this cluster. The sample includes 1447 galaxies with measured redshifts within 60' from the cluster center (1148 from this MMT/Hectospec program and 299 from the literat…
New Catalog of Distances to Planetary Nebulae Based on Gaia Parallaxes and Statistical Distances
Peña, M.; Rodríguez, M.; Hernández-Juárez, D.
We have developed a method to determine the most reliable distances for a large group of planetary nebulae. For this purpose, we analyze the distances obtained from Gaia parallaxes and three determinations of statistical distances. The most reliable distance is derived for 2211 objects, and uncertainties for these distances are calculated in a hom…
Observational study of intermittent solar jets: p-mode modulation
Liu, Yang; Cao, Wenda; Schmieder, Brigitte +7 more
Aims: Recurring jets are observed in the solar atmosphere. They can erupt intermittently over a long period of time. By the observation of intermittent jets, we wish to understand what causes the characteristics of the periodic eruptions.
Methods: We report intermittent jets observed by the Goode Solar Telescope (GST) with the TiO Broadb…
A Quantification of the Effects Using Different Stellar-population Synthesis Models for Epoch of Reionization
Luo, Rongxin; Han, Yunkun; Liu, Peiai +1 more
The luminosity and spectral energy distribution of high-z galaxies are sensitive to the stellar-population synthesis (SPS) models. In this paper, we study the effects of different SPS models on the measurements of high-z galaxies and the budget of ionizing photons during the epoch of reionization by employing each of them in the semianalytical gal…
Three-dimensional Atmospheric Dynamics of Jupiter from Ground-based Doppler Imaging Spectroscopy in the Visible
Wong, Michael H.; Izumiura, Hideyuki; Sato, Bun'ei +25 more
We present three-dimensional (3D) maps of Jupiter's atmospheric circulation at cloud-top level from Doppler-imaging data obtained in the visible domain with JIVE, the second node of the JOVIAL network, which is mounted on the Dunn Solar Telescope at Sunspot, New Mexico. We report on 12 nights of observations between 2018 May 4 and May 30, represen…
Recovery of coronal dimmings
Veronig, A. M.; Podladchikova, T.; Chikunova, G. +2 more
Context. Coronal dimmings are regions of reduced emission in the lower corona observed in the wake of coronal mass ejections (CMEs), representing their footprints. Studying the lifetime evolution of coronal dimmings helps us to better understand the recovery and replenishment of the corona after large-scale eruptions. Aims. We study the recovery o…
TESS Hunt for Young and Maturing Exoplanets (THYME). X. A Two-planet System in the 210 Myr MELANGE-5 Association
Vanderburg, Andrew; Triaud, Amaury H. M. J.; Quinn, Samuel N. +35 more
Young (<500 Myr) planets are critical to studying how planets form and evolve. Among these young planetary systems, multiplanet configurations are particularly useful, as they provide a means to control for variables within a system. Here, we report the discovery and characterization of a young planetary system, TOI-1224. We show that the plane…
Measuring the intracluster medium velocity structure within the A3266 galaxy cluster
Pinto, C.; Eckert, D.; Gatuzz, E. +7 more
We present a detailed analysis of the velocity structure of the hot intracluster medium (ICM) within the A3266 galaxy cluster, including new observations taken between June and November 2023. Firstly, morphological structures within the galaxy cluster were examined using a Gaussian gradient magnitude (GGM) and an adaptively smoothed GGM filter app…
Early photometric and spectroscopic observations of the extraordinarily bright INTEGRAL-detected GRB 221009A
Sánchez-Ramírez, R.; Pandey, S. B.; Castro-Tirado, A. J. +46 more
Context. GRB 221009A, initially detected as an X-ray transient by Swift, was later revealed to have triggered the Fermi satellite about an hour earlier, marking it as a post-peak observation of the event's emission. This GRB distinguished itself as the brightest ever recorded, presenting an unparalleled opportunity to probe the complexities of GRB…
