High-quality Extragalactic Legacy-field Monitoring (HELM) with DECam
Ming-Yang Zhuang, Qian Yang, Yue Shen +45
High-quality Extragalactic Legacy-field Monitoring (HELM) is a long-term observing program that photometrically monitors several well-studied extragalactic legacy fields with the D…
Spatially resolved microlensing timescale distributions across the Galactic bulge with the VVV survey
Zofia Kaczmarek, Peter McGill, N. Wyn Evans +5
We analyze 1602 microlensing events found in the VISTA Variables in the Via Lactea (VVV) near-infrared (NIR) survey data. We obtain spatially-resolved, efficiency-corrected timesca…
Distribution of H-alpha Emitters in Merging Galaxy Clusters
David Wittman, Dariush Imani, Rutger Hartmann Olden +1
Studies of star formation in various galaxy cluster mergers have reached apparently contradictory conclusions regarding whether mergers stimulate star formation, quench it, or have…
Primordial Black Hole Dark Matter Simulations Using PopSyCLE
K. Pruett, W. Dawson, M. S. Medford +6
Primordial black holes (PBHs), theorized to have originated in the early universe, are speculated to be a viable form of dark matter. If they exist, they should be detectable throu…
Exemplary Merging Clusters: Weak-lensing and X-ray Analysis of the Double Radio Relic Merging Galaxy Clusters MACS 1752.0+4440 and ZWCL 1856.8+6616
Kyle Finner, Kim HyeongHan, M. James Jee +8
The investigation of merging galaxy clusters that exhibit radio relics is strengthening our understanding of the formation and evolution of galaxy clusters, the nature of dark matt…
A Reanalysis of Public Galactic Bulge Gravitational Microlensing Events from OGLE-III and IV
Nathan Golovich, William A. Dawson, Fran Bartolić +8
Modern surveys of gravitational microlensing events have progressed to detecting thousands per year. Surveys are capable of probing Galactic structure, stellar evolution, lens popu…
Deep Very Large Array observations of the merging cluster CIZA J2242.8+5301: continuum and spectral imaging
G. Di Gennaro, R. J. van Weeren, M. Hoeft +14
Despite progress in understanding radio relics, there are still open questions regarding the underlying particle acceleration mechanisms. In this paper we present deep 1--4 GHz VLA…
MC: Multi-wavelength and dynamical analysis of the merging galaxy cluster ZwCl 0008.8+5215: An older and less massive Bullet Cluster
Nathan Golovich, Reinout J. van Weeren, William A. Dawson +2
We analyze a rich dataset including Subaru/SuprimeCam, HST/ACS and WFC3, Keck/DEIMOS, Chandra/ACIS-I, and JVLA/C and D array for the merging galaxy cluster ZwCl 0008.8+5215. With a…
MC^2: Galaxy Imaging and Redshift Analysis of the Merging Cluster CIZA J2242.8+5301
William A. Dawson, M. James Jee, Andra Stroe +7
X-ray and radio observations of CIZA J2242.8+5301 suggest that it is a major cluster merger. Despite being well studied in the X-ray, and radio, little has been presented on the cl…
