Cross-Scale Quantification of Storm-Time Dayside Magnetospheric Magnetic Flux Content
Le Contel, O.; Fontaine, D.; Akhavan-Tafti, M. +2 more
A clear understanding of storm-time magnetospheric dynamics is essential for a reliable storm forecasting capability. The dayside magnetospheric response to an interplanetary coronal mass ejection (ICME; dynamic pressure Pdyn > 20 nPa and storm-time index SYM-H < -150 nT) is investigated using in situ OMNI, Geotail, Cluster, MMS, …
ALMA twenty-six arcmin2 survey of GOODS-S at one millimeter (ASAGAO): Millimeter properties of stellar mass selected galaxies
Ouchi, Masami; Fujimoto, Seiji; Tamura, Yoichi +19 more
We make use of the ALMA twenty-Six Arcmin2 survey of GOODS-S At One-millimeter (ASAGAO), deep 1.2 mm continuum observations of a 26-arcmin2 region in the Great Observatories Origins Deep Survey-South (GOODS-S) obtained with Atacama Large Millimeter/sub-millimeter Array (ALMA), to probe dust-enshrouded star formation in K-band…
Updated Equipotential Shapes of Jupiter and Saturn Using Juno and Cassini Grand Finale Gravity Science Measurements
Helled, Ravit; Folkner, William M.; Parisi, Marzia +2 more
A commonly used shape model for the giant plants of Jupiter and Saturn is an oblate ellipsoid, a simplified model of the equipotential shape. The ellipsoidal shape models were originally derived from radio occultation data and gravity data after the Voyager flybys in 1979. Through precise Doppler tracking of NASA's Juno and Cassini spacecraft tele…
The molecular mass function of the local Universe
Andreani, P.; Boselli, A.; Vio, R. +4 more
Aims: We construct the molecular mass function using the bivariate K-band-mass function (BMF) of the Herschel Reference Survey (HRS), which is a volume-limited sample that has already been widely studied at the entire electromagnetic spectrum.
Methods: The molecular mass function was derived from the K-band and the gas mass cumulative di…
Hα Distances to the Leading Arm of the Magellanic Stream
Antwi-Danso, Jacqueline; Barger, Kathleen A.; Haffner, L. Matthew
The Leading Arm (LA) is a tidal feature that is in front of the Magellanic Clouds (MCs) on their orbit through the Galaxy's halo. Many physical properties of the LA, such as its mass and size, are poorly constrained because it has few distance measurements. While Hα measurements have been used to estimate the distances to halo clouds, many studies…
A Catalog of Emission-line Galaxies from the Faint Infrared Grism Survey: Studying Environmental Influence on Star Formation
Finkelstein, Steven L.; Hathi, Nimish; Windhorst, Rogier +18 more
We present a catalog of 208 0.3 < z < 2.1 emission-line galaxies (ELGs) selected from 1D slitless spectroscopy obtained using Hubble’s WFC3 G102 grism, as part of the Faint Infrared Grism Survey. We identify ELG candidates by searching for significant peaks in all continuum-subtracted G102 spectra and, where possible, confirm candidates by i…
Doppler shift oscillations of a sunspot detected by CYRA and IRIS
Li, D.; Su, J. T.; Cao, W. +4 more
Context. The carbon monoxide (CO) molecular line at around 46655 Å in solar infrared spectra is often used to investigate the dynamic behavior of the cold heart of the solar atmosphere, i.e., sunspot oscillation, especially at the sunspot umbra.
Aims: We investigated sunspot oscillation at Doppler velocities of the CO 7-6 R67 and 3-2 R14 line…
The Elusive Distance Gradient in the Ultrafaint Dwarf Galaxy Hercules: A Combined Hubble Space Telescope and Gaia View
Strader, Jay; Seth, Anil C.; Sand, David J. +6 more
The ultrafaint dwarf galaxy Hercules has an extremely elongated morphology with both photometric overdensities and kinematic members at large radii, suggesting that it may be tidally disrupting due to a previous close encounter with the Milky Way. To explain its observational peculiarities, we present a deep Hubble Space Telescope (HST) imaging st…
Reconstruction of Extreme Geomagnetic Storms: Breaking the Data Paucity Curse
Merkin, V. G.; Sitnov, M. I.; Roelof, E. C. +5 more
Reconstruction of the magnetic field, electric current, and plasma pressure is provided using a new data mining (DM) method with weighted nearest neighbors (NN) for strong storms with the storm activity index Sym-H < -300 nT, the Bastille Day event (July 2000), and the 20 November 2003 superstorm. It is shown that the new method significantly r…
Physical conditions of five O VI absorption systems towards PG 1522+101
Savage, Blair D.; Wakker, Bart P.; Charlton, Jane +4 more
We present the analysis of five O VI absorbers identified across a redshift path of z ~ (0.6-1.3) towards the background quasar PG 1522+101 with information on five consecutive ionization stages of oxygen from O II to O VI. The combined HST and Keck spectra cover UV, redshifted extreme-UV, and optical transitions from a multitude of ions spanning …
