Gaia-assisted discovery of a detached low-ionisation BAL quasar with very large ejection velocities
J. P. U. Fynbo, P. Møller, K. E. Heintz +10
We report on the discovery of a peculiar Broad Absorption Line (BAL) quasar identified in our Gaia-assisted survey of red quasars. The systemic redshift of this quasar was difficul…
The Detectability and Constraints of Biosignature Gases in the Near & Mid-Infrared from Transit Transmission Spectroscopy
Luke Tremblay, Michael R Line, Kevin B Stevenson +4
The James Webb Space Telescope (JWST) is expected to revolutionize our understanding of Jovian worlds over the coming decade. However, as we push towards characterizing cooler, sma…
TOI 564 b and TOI 905 b: Grazing and Fully Transiting Hot Jupiters Discovered by TESS
Allen B. Davis, Songhu Wang, Matias Jones +46
We report the discovery and confirmation of two new hot Jupiters discovered by the Transiting Exoplanet Survey Satellite (TESS): TOI 564 b and TOI 905 b. The transits of these two…
X-ray spectral and flux variability of the microquasar GRS 1758-258 on timescales from weeks to years
Maria Hirsch, Katja Pottschmidt, David M. Smith +12
We present the spectral and timing evolution of the persistent black hole X-ray binary GRS 1758-258 based on almost 12 years of observations using the Rossi X-ray Timing Explorer P…
Is Big Data Performance Reproducible in Modern Cloud Networks?
Alexandru Uta, Alexandru Custura, Dmitry Duplyakin +5
Performance variability has been acknowledged as a problem for over a decade by cloud practitioners and performance engineers. Yet, our survey of top systems conferences reveals th…
Evidence for a Dichotomy in the Interior Structures of Jupiter and Saturn from Helium Phase Separation
Christopher R. Mankovich, Jonathan J. Fortney
We examine the comparative thermal evolution of Jupiter and Saturn applying recent theoretical results for helium's immiscibility in fluid metallic hydrogen. The redistribution of…
The Distribution of Ultra-Diffuse and Ultra-Compact Galaxies in the Frontier Fields
Steven R. Janssens, Roberto Abraham, Jean Brodie +2
Large low surface brightness galaxies have recently been found to be abundant in nearby galaxy clusters. In this paper, we investigate these ultra-diffuse galaxies (UDGs) in the si…
On the dynamics characterization of complex projective spaces
Mita Banik
We show that a closed weakly-monotone symplectic manifold of dimension which has minimal Chern number greater than or equal to and admits a Hamiltonian toric pseudo-rota…
Symmetry breaking, strain solitons and mechanical edge modes in monolayer antimony
Joshua Chiel, Harsh Mathur, Onuttom Narayan
Two-dimensional materials exhibit a variety of mechanical instabilities accompanied by spontaneous symmetry breaking. Here we develop a continuum description of the buckling instab…
Efficiently Counting Vertex Orbits of All 5-vertex Subgraphs, by EVOKE
Noujan Pashanasangi, C. Seshadhri
Subgraph counting is a fundamental task in network analysis. Typically, algorithmic work is on total counting, where we wish to count the total frequency of a (small) pattern subgr…
Probing the Properties of the Pulsar Wind in the Gamma-Ray Binary HESS J0632+057 with NuSTAR and VERITAS Observations
A. Archer, W. Benbow, R. Bird +60
HESS J0632+057 is a gamma-ray binary composed of a compact object orbiting a Be star with a period of about days. Extensive X-ray and TeV gamma-ray observations have revealed…
The Subaru HSC Galaxy Clustering with Photometric Redshift I: Dark Halo Masses Versus Baryonic Properties of Galaxies at 0.3<z<1.4
Shogo Ishikawa, Nobunari Kashikawa, Masayuki Tanaka +8
We present the clustering properties of low- galaxies selected by the Hyper Suprime-Cam Subaru Strategic Program Wide layer over deg. The wide-field and…
Loop Dominated Signals from Neutrino Portal Dark Matter
Hiren H. Patel, Stefano Profumo, Bibhushan Shakya
We study scenarios where loop processes give the dominant contributions to dark matter decay or annihilation despite the presence of tree level channels. We illustrate this possibi…
A Catalog of M-dwarf Flares with ASAS-SN
Romy Rodríguez Martínez, Laura A. Lopez, Benjamin J. Shappee +5
We analyzed the light curves of 1376 early-to-late, nearby M dwarfs to search for white-light flares using photometry from the All-Sky Automated Survey for Supernovae (ASAS-SN). We…
A hidden friend for the galactic center black hole, Sgr A*
Smadar Naoz, Clifford M. Will, Enrico Ramirez-Ruiz +3
The hierarchical nature of galaxy formation suggests that a supermassive black hole binary could exist in our galactic center. We propose a new approach to constraining the possibl…
Large Scale Structures in the CANDELS Fields: The Role of the Environment in Star Formation Activity
Nima Chartab, Bahram Mobasher, Behnam Darvish +14
We present a robust method, weighted von Mises kernel density estimation, along with boundary correction to reconstruct the underlying number density field of galaxies. We apply th…
The Activation of Galactic Nuclei and Their Accretion Rates are Linked to the Star Formation Rates and Bulge-types of Their Host Galaxies
Hassen M. Yesuf, S. M. Faber, David C. Koo +3
We use bulge-type classifications of 809 representative SDSS galaxies by Gadotti (2009) to classify a large sample of galaxies into real bulges (classical or elliptical) and pseudo…
Elemental Abundances in M31: The Kinematics and Chemical Evolution of Dwarf Spheroidal Satellite Galaxies
Evan N. Kirby, Karoline M. Gilbert, Ivanna Escala +4
We present deep spectroscopy from Keck/DEIMOS of Andromeda I, III, V, VII, and X, all of which are dwarf spheroidal satellites of M31. The sample includes 256 spectroscopic members…
Saturn's Probable Interior: An Exploration of Saturn's Potential Interior Density Structures
Naor Movshovitz, Jonathan J. Fortney, Chris Mankovich +2
The gravity field of a giant planet is typically our best window into its interior structure and composition. Through comparison of a model planet's calculated gravitational potent…
Momentum Injection by Clustered Supernovae: Testing Subgrid Feedback Prescriptions
Eric S. Gentry, Piero Madau, Mark R. Krumholz
Using a 1D Lagrangian code specifically designed to assess the impact of multiple, time-resolved supernovae (SNe) from a single star cluster on the surrounding medium, we test thre…
