商品描述

This thesis presents a novel analysis of a photometric observational feature of Type Ia Supernovae (SNe Ia), the most precise distance indicators available for cosmological studies. While SNe Ia are crucial for understanding modern cosmology, there are systematic uncertainties associated with them that prevent use to their full potential. It is therefore vital that sources of systematic error in SN Ia standardization are better understood. In this thesis, the author robustly connects the color-magnitude diagram to SN Ia spectra and their physics for the first time, and shows that for the SN sample in the dissertation, this feature is important to consider as a contributor to scatter in the Hubble residual. There is no prior work in the literature that examines this feature in such depth, and it is rare to be able to paint such a thorough picture in a SN Ia study rooted in a single photometric feature. This work opens up many avenues for future observational and theoretical studies.

商品描述(中文翻譯)

本論文提出了一種對 Ia 型超新星（SNe Ia）光度觀測特徵的新穎分析，SNe Ia 是可用於宇宙學研究的最精確距離指標。雖然 SNe Ia 對於理解現代宇宙學至關重要，但與之相關的系統性不確定性卻阻礙了其潛力的充分發揮。因此，深入了解 SN Ia 標準化中的系統性誤差來源至關重要。在本論文中，作者首次穩健地將顏色-絕對星等圖與 SN Ia 光譜及其物理學聯繫起來，並顯示對於論文中的 SN 樣本，這一特徵在考慮哈勃殘差的散布時是重要的。文獻中尚無先前的研究對此特徵進行如此深入的探討，並且在基於單一光度特徵的 SN Ia 研究中能夠如此全面地描繪出來是相當罕見的。這項工作為未來的觀測和理論研究開啟了許多途徑。

作者簡介

Lauren Aldoroty is a postdoctoral research associate at Duke University, where their research focuses on supernova cosmology using data from NASA's upcoming Nancy Grace Roman Space Telescope. They especially enjoy any chance they get to write useful code, and going on about why we should all care more about supernova physics. Dr. Aldoroty graduated from Texas A&M University with a Ph.D. in astronomy. They also hold a B.S. in physics from Johns Hopkins University. In their spare time, Dr. Aldoroty enjoys having zero spare time due to picking up far too many hobbies. Some of Dr. Aldoroty's lifelong, core-personality-level interests include horses, rifle shooting, and drawing. Some of their more recent interests include vegan baking, pottery, and drinking fancy tea.
