MOSEL Survey: Tracking the Growth of Massive Galaxies at 2 < z < 4 Using Kinematics and the IllustrisTNG Simulation
Papovich, Casey; Kewley, Lisa J.; Harshan, Anishya +13 more
We use K-band spectroscopic data from the Multi-Object Spectroscopic Emission Line survey to analyze the kinematic properties of galaxies at z > 3. Our sample consists of 34 galaxies at 3.0 < zspec < 3.8 between 9.0 < $\mathrm{log}({M}_{* }/{M}_{\odot })$ < 11.0. We find that galaxies with $\mathrm{log}({M}_{* }/{M}_{\odo…
Intercycle and Intracycle Variation of Halo CME Rate Obtained from SOHO/LASCO Observations
Gopalswamy, Nat; Akiyama, Sachiko; Yashiro, Seiji +3 more
We report on the properties of halo coronal mass ejections (HCMEs) in solar cycles 23 and 24. We compare the HCME properties between the corresponding phases (rise, maximum, and declining) in cycles 23 and 24 and compare those between the whole cycles. Despite the significant decline in the sunspot number (SSN) in cycle 24, which dropped by 46% wi…
Study of Star Clusters in the M83 Galaxy with a Convolutional Neural Network
Bialopetravičius, Jonas; Narbutis, Donatas
We present a study of evolutionary and structural parameters of star cluster candidates in the spiral galaxy M83. For this we use a convolutional neural network trained on mock clusters and capable of fast identification and localization of star clusters, as well as inference of their parameters from multiband images. We use this pipeline to detec…
XMM-Newton observations of a gamma-ray pulsar J0633+0632: pulsations, cooling and large-scale emission
Zyuzin, D.; Danilenko, A.; Karpova, A. +2 more
We report results of XMM-Newton observations of a γ-ray pulsar J0633+0632 and its wind nebula. We reveal, for the first time, pulsations of the pulsar X-ray emission with a single sinusoidal pulse profile and a pulsed fraction of 23 ± 6 per cent in the 0.3-2 keV band. We confirm previous Chandra findings that the pulsar X-ray spectrum consists of …
Unraveling the Physics of Quasar Jets: Optical Polarimetry and Implications for the X-ray Emission Process
Perlman, Eric S.; Clautice, Devon; Avachat, Sayali +4 more
Since the launch of Chandra twenty years ago, one of the greatest mysteries surrounding Quasar Jets is the production mechanism for their extremely high X-ray luminosity. Two mechanisms have been proposed. In the first view, the X-ray emission is inverse-Comptonized CMB photons. This view requires a jet that is highly relativistic (bulk Lorentz fa…
Future Missions Related to the Determination of the Elemental and Isotopic Composition of Earth, Moon and the Terrestrial Planets
Sotin, Christophe; Guenther, Eike W.; Dandouras, Iannis +14 more
In this chapter, we review the contribution of space missions to the determination of the elemental and isotopic composition of Earth, Moon and the terrestrial planets, with special emphasis on currently planned and future missions. We show how these missions are going to significantly contribute to, or sometimes revolutionise, our understanding o…
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…
