Astronomical CH3+ rovibrational assignments. A combined theoretical and experimental study validating observational findings in the d203-506 UV-irradiated protoplanetary disk
Martin-Drumel, Marie-Aline; Van De Putte, Dries; Habart, Emilie +25 more
Context. The methyl cation (CH3+) has recently been discovered in the interstellar medium through the detection of 7 µm (1400 cm−1) features toward the d203-506 protoplanetary disk by the JWST. Line-by-line spectroscopic assignments of these features, however, were unsuccessful due to complex intramolecular p…
Applying Magnetic Curvature to MMS Data to Identify Thin Current Sheets Relative to Tail Reconnection
Farrugia, C. J.; Torbert, R. B.; Rogers, A. J. +1 more
Thin current sheets (TCSs) have been postulated to be a necessary precondition for reconnection onset. Magnetic reconnection X-lines in the magnetotail have been observed to be more common duskward of midnight. We take advantage of the MMS tetrahedral formation during the 2017-2020 MMS tail seasons to calculate the thickness of the cross-tail neut…
The Roles of Morphology and Environment on the Star Formation Rate-Stellar Mass Relation in COSMOS from 0 < z < 3.5
Kartaltepe, Jeyhan S.; Koekemoer, Anton M.; Peng, Ying-jie +6 more
We investigate the relationship between environment, morphology, and the star formation rate (SFR)-stellar mass relation derived from a sample of star-forming (SF) galaxies (commonly referred to as the "star formation main sequence", SFMS) in the COSMOS field from 0 < z < 3.5. We constructed and fit the far-UV-far-IR spectral energy distribu…
Spatially resolved mock observations of stellar kinematics: full radiative transfer treatment of simulated galaxies
Straatman, Caroline M. S.; van der Wel, Arjen; Bezanson, Rachel +6 more
We present a framework to build realistic mock spectroscopic observations for state-of-the-art hydrodynamical simulations, using high spectral resolution stellar population models and full radiative transfer treatment with SKIRT. As a first application, we generate stellar continuum mock observations for the Auriga cosmological zoom simulations em…
Taking a break: Paused accretion in the symbiotic binary RT Cru
Nuñez, N. E.; Mukai, K.; Sokoloski, J. L. +10 more
Symbiotic binaries sometimes hide their symbiotic nature for significant periods of time. There is mounting observational evidence that, in symbiotics that are powered solely by the accretion of the red giant's wind material onto a white dwarf, without any quasi-steady shell burning on the surface of the white dwarf, the characteristic emission li…
Persistent and occasional: Searching for the variable population of the ZTF/4MOST sky using ZTF Data Release 11
Bayo, A.; Bauer, F. E.; Arévalo, P. +13 more
Aims: We present a variability-, color-, and morphology-based classifier designed to identify multiple classes of transients and persistently variable and non-variable sources from the Zwicky Transient Facility (ZTF) Data Release 11 (DR11) light curves of extended and point sources. The main motivation to develop this model was to identify ac…
WIYN Open Cluster Study 89. M48 (NGC 2548) 2: Lithium Abundances in the 420 Myr Open Cluster M48 from Giants through K Dwarfs
Twarog, Bruce A.; Anthony-Twarog, Barbara J.; Deliyannis, Constantine P. +2 more
We consider WIYN/Hydra spectra of 329 photometric candidate members of the 420 Myr old open cluster M48 and report lithium detections or upper limits for 234 members and likely members. The 171 single members define a number of notable Li-mass trends, some delineated even more clearly than in Hyades/Praesepe: the giants are consistent with subgian…
Big Three Dragons: Molecular Gas in a Bright Lyman-break Galaxy at z = 7.15
Ono, Yoshiaki; Fujimoto, Seiji; Harikane, Yuichi +11 more
We report Atacama Large Millimeter/submillimeter Array Band 3 observations of CO(6-5), CO(7-6), and [C I](2-1) in B14-65666 ("Big Three Dragons"), one of the brightest Lyman-break galaxies at z > 7 in the rest-frame ultraviolet continuum, far-infrared continuum, and emission lines of [O III] 88 µm and [C II] 158 µm. CO(6-5), CO(7-6)…
Tracing the kinematics of the whole ram-pressure-stripped tails in ESO 137-001
Fumagalli, Michele; Fossati, Matteo; Sun, Ming +8 more
Ram pressure stripping (RPS) is an important process to affect the evolution of cluster galaxies and their surrounding environment. We present a large MUSE mosaic for ESO 137-001 and its stripped tails, and study the detailed distributions and kinematics of the ionized gas and stars. The warm, ionized gas is detected to at least 87 kpc from the ga…
The Breakthrough Listen Search for Intelligent Life: A Laser Search Pipeline for the Automated Planet Finder
Croft, Steve; Isaacson, Howard; Siemion, Andrew +4 more
The Search for Extraterrestrial Intelligence has traditionally been conducted at radio wavelengths, but optical searches are well-motivated and increasingly feasible due to the growing availability of high-resolution spectroscopy. We present a data analysis pipeline to search Automated Planet Finder (APF) spectroscopic observations from the Levy S…
