Two sets of White Paper submissions, Science and APC¹, are available in response to the Astro2020 Decadal Survey. CSV files of info on them are available at that site. I took those source files and created searchable HTML pages with links to the PDF files for each paper. What's searchable is the paper title, the principal author and their institution, a short description of the paper, and (for the Science White Papers) the NASA ADS Bibcode record. The ADS data was extracted from an AAS Bulletin.

Each of the two searchable webpages has a link to the other, as well as to the source data. The webpages are self-contained with all the data included in the html file, which contains the javascript code for the searches and the CSS for styling.

The original purpose in doing this was because many of the submissions were not on the arXiv, and I wanted to see what else was available and also so the PDF file link were all on one page. In addition, though, the search feature has been very useful.

New developments since this post was originally created: videos of presentations at the KITP-UCSB conference Tensions between the Early and the Late Universe in mid-July 2019: (1) Tomasso Treu presentation: Time delay cosmography and the Hubble constant tension, and (2) Anowar J. Shajib presentation: Towards a 1% Hubble constant measurement with time delay cosmography. ___

This paper [arxiv: 1902.03261] is a current status review on improving systematics¹ in SNe Ia distance measurements by combining optical with near-infrared (NIR) photometry. Though initially being done at low redshifts (z <= 0.04), there are plans to extend this work to higher redshifts². The paper is authored by some of the more noted researchers in this area, e.g., Arturo Avelino and Robert Kirshner³. My goal here is a top-level summary, so that if you don't read the paper you'll hopefully get the gist of it, while also including helpful supplemental info. In a few cases, I added some font bolding for emphasis.

“This is significant for supernova cosmology because, along with photometric-calibration uncertainties, uncertain dust [extinction](https://en.wikipedia.org/wiki/Extinction_(astronomy) estimates and the intrinsic variability of SN Ia colors present challenging and important systematic problems for dark energy measurements. (pg2)”

“Recent work has demonstrated that SN Ia in the NIR are more nearly standard candles, even before correction for light curve (LC) shape or host galaxy dust reddening... Overall, a substantial body of evidence indicates that rest-frame LCs of SN Ia in NIR are both better standard candles than at optical wavelengths and less sensitive to the confounding effects of dust. When NIR data are combined with UBV RI photometry, this yields accurate and precise distance estimates. (pg2)”
