EmpiriciSN: Re-sampling Observed Supernova/Host Galaxy Populations using an XD Gaussian Mixture Model
Thomas W. -S. Holoien, Philip J. Marshall, Risa H. Wechsler
We describe two new open source tools written in Python for performing extreme deconvolution Gaussian mixture modeling (XDGMM) and using a conditioned model to re-sample observed s…
Red nuggets grow inside-out: evidence from gravitational lensing
Lindsay Oldham, Matt Auger, Chris Fassnacht +7
We present a new sample of strong gravitational lens systems where both the foreground lenses and background sources are early-type galaxies. Using imaging from HST/ACS and Keck/NI…
H0LiCOW VI. Testing the fidelity of lensed quasar host galaxy reconstruction
Xuheng Ding, Kai Liao, Tommaso Treu +11
The empirical correlation between the mass of a super-massive black hole (MBH) and its host galaxy properties is widely considered to be evidence of their co-evolution. A powerful…
Maximizing Science in the Era of LSST: A Community-Based Study of Needed US Capabilities
Joan Najita, Beth Willman, Douglas P. Finkbeiner +48
The Large Synoptic Survey Telescope (LSST) will be a discovery machine for the astronomy and physics communities, revealing astrophysical phenomena from the Solar System to the out…
Spectral analysis of four 'hypervariable' AGN: a microneedle in the haystack?
A. Bruce, A. Lawrence, C. MacLeod +13
We analyze four extreme active galactic nuclei (AGN) transients to explore the possibility that they are caused by rare, high-amplitude microlensing events. These previously unknow…
H0LiCOW III. Quantifying the effect of mass along the line of sight to the gravitational lens HE 0435-1223 through weighted galaxy counts
Cristian E. Rusu, Christopher D. Fassnacht, Dominique Sluse +8
Based on spectroscopy and multiband wide-field observations of the gravitationally lensed quasar HE 0435-1223, we determine the probability distribution function of the external co…
H0LiCOW IV. Lens mass model of HE 0435-1223 and blind measurement of its time-delay distance for cosmology
Kenneth C. Wong, Sherry H. Suyu, Matthew W. Auger +13
Strong gravitational lenses with measured time delays between the multiple images allow a direct measurement of the time-delay distance to the lens, and thus a measure of cosmologi…
H0LiCOW II. Spectroscopic survey and galaxy-group identification of the strong gravitational lens system HE0435-1223
D. Sluse, A. Sonnenfeld, N. Rumbaugh +15
Galaxies located in the environment or on the line of sight towards gravitational lenses can significantly affect lensing observables, and can lead to systematic errors on the meas…
H0LiCOW I. Lenses in COSMOGRAIL's Wellspring: Program Overview
S. H. Suyu, V. Bonvin, F. Courbin +21
Strong gravitational lens systems with time delays between the multiple images allow measurements of time-delay distances, which are primarily sensitive to the Hubble constant that…
Time Delay Cosmography
Tommaso Treu, Philip J. Marshall
Gravitational time delays, observed in strong lens systems where the variable background source is multiply-imaged by a massive galaxy in the foreground, provide direct measurement…
Slow blue nuclear hypervariables in PanSTARRS-1
A. Lawrence, A. G. Bruce, C. MacLeod +23
We discuss 76 large amplitude transients (Delta-m>1.5) occurring in the nuclei of galaxies, nearly all with no previously known Active Galactic Nucleus (AGN). They have been discov…
Detection of lensing substructure using ALMA observations of the dusty galaxy SDP.81
Yashar D. Hezaveh, Neal Dalal, Daniel P. Marrone +13
We study the abundance of substructure in the matter density near galaxies using ALMA Science Verification observations of the strong lensing system SDP.81. We present a method to…
