SN 2021hpr: A Normal Type Ia Supernova Showing Excess Emission in the Early Rising Phase
Abdusamatjan Iskandar, Xiaofeng Wang, Ali Esamdin +37
We present extensive optical observations of a nearby Type Ia supernova (SN Ia), SN 2021hpr, located in the spiral galaxy NGC 3147 at a distance of 45 Mpc. Our observations…
The Pantheon+ Analysis: The Full Dataset and Light-Curve Release
Dan Scolnic, Dillon Brout, Anthony Carr +27
Here we present 1701 light curves of 1550 spectroscopically confirmed Type Ia supernovae (SNe Ia) that will be used to infer cosmological parameters as part of the Pantheon+ SN ana…
SN 2021csp -- the explosion of a stripped envelope star within a H and He-poor circumstellar medium
Morgan Fraser, Maximilian D. Stritzinger, Sean J. Brennan +48
We present observations of SN 2021csp, a unique supernova (SN) which displays evidence for interaction with H- and He- poor circumstellar material (CSM) at early times. Using high-…
SALT3: An Improved Type Ia Supernova Model for Measuring Cosmic Distances
W. D. Kenworthy, D. O. Jones, M. Dai +13
A spectral-energy distribution (SED) model for Type Ia supernovae (SNe Ia) is a critical tool for measuring precise and accurate distances across a large redshift range and constra…
The Foundation Supernova Survey: Photospheric Velocity Correlations in Type Ia Supernovae
Kyle G. Dettman, Saurabh W. Jha, Mi Dai +14
The ejecta velocities of type-Ia supernovae (SNe Ia), as measured by the Si II line, have been shown to correlate with other supernova properties, including color and stand…
The Foundation Supernova Survey: Measuring Cosmological Parameters with Supernovae from a Single Telescope
D. O. Jones, D. M. Scolnic, R. J. Foley +27
Measurements of the dark energy equation-of-state parameter, , have been limited by uncertainty in the selection effects and photometric calibration of Type Ia supernova…
Rigid colourings of hypergraphs and contiguity
Peter Ayre, Catherine Greenhill
We consider the problem of -colouring a -uniform random hypergraph, where , and determine the rigidity threshold. For edge densities above the rigidity threshold,…
Should Type Ia Supernova Distances be Corrected for their Local Environments?
D. O. Jones, A. G. Riess, D. M. Scolnic +13
Recent analyses suggest that distance residuals measured from Type Ia supernovae (SNe Ia) are correlated with local host galaxy properties within a few kpc of the SN explosion. How…
The Foundation Supernova Survey: Motivation, Design, Implementation, and First Data Release
Ryan J. Foley, Daniel Scolnic, Armin Rest +25
The Foundation Supernova Survey aims to provide a large, high-fidelity, homogeneous, and precisely-calibrated low-redshift Type Ia supernova (SN Ia) sample for cosmology. The calib…
Kepler Monitoring of an L Dwarf II. Clouds with Multiyear Lifetimes
John E. Gizis, Kyle G. Dettman, Adam J. Burgasser +7
We present Kepler, Spitzer Space Telescope, Gemini-North, MMT, and Kitt Peak observations of the L1 dwarf WISEP J190648.47+401106.8. We find that the Kepler optical light curve is…
