2021/2022 Robert E. Kennedy Library Annual Report
Get PDFThis year’s stories highlight successes and transformations, which will remain woven into the fabric of our organization. Instituting contactless pick-up for library materials is an example of learning how to quickly bring together people to solve immediate problems. We also became more effective at engaging with our constituencies. We reached more users through virtual consultations and online reference assistance and helped them get access to the expertise and materials they needed. We opened access to special collections through on-demand digitization. We broke barriers in the adoption of digital resources for teaching. And we began the challenging work of developing a community-based, critical, anti-racist peer-review culture
Guidelines for the EERI Seismic Design Competition
Get PDFThe Earthquake Engineering Research Institute (EERI) has been dedicated to exposing undergraduate students to the wide range of interdisciplinary subjects related to earthquake engineering through the Seismic Design Competition. In 2022, California Polytechnic State University, San Luis Obispo (Cal Poly) sent 14 students to Salt Lake City, Utah for the competition – to compete with 31 other teams who all tackled the competition problem statement uniquely. The 2022 team was tasked with the research, design, analysis, and construction of a new structure to be built in downtown Salt Lake City, with the goal of replicating the design sequence of real-world engineering. The following report outlines the preparation, organization, and timeline taken by the Cal Poly team in advance of the seismic design competition, with the intent of guiding future EERI teams. It should be noted that this report is not only intended to serve as a guide for future students, but also will explain the demand of interdisciplinary subjects in the competition in hopes of attracting undergraduate students who are interested in broadening their vision of engineering to participate in the competition. For public access, this document, including additional supplementary materials, will be available in the Cal Poly Digital Commons
Traducciones para el Colegio de la Facultad de Ingeniería (CENG) del Inglés al Español / College of Engineering Translations
No full textThis project seeks to show how I managed to translate texts from English to Spanish through the process of learning the concept of translation. It specifically seeks to demonstrate how to accurately translate a notion or message from one language to another without creating misunderstandings or errors. This project includes documents from the College of Engineering at Cal Poly, that I translated from English to Spanish in the hopes that members of the Hispanic community will be able to access them and learn more about the various study options the College of Engineering offers. We live in a very diverse world that keeps changing and evolving and as a result we have changed our ways of communicating and how we access information. Because we live in a very diverse society it is necessary to provide information in the main languages the public communicates in to build a strong community.
Using the comprehensive and intercultural competency abilities I\u27ve picked up from my courses and instructors, my project portrays my experience as a WLC student. I think the information and abilities I\u27ve acquired and developed have aided me in forging deep bonds with local and international communities. These abilities enable us to increase our employment and professional opportunities and improve our education and travel opportunities. My project aims to clarify the purpose of translation, the significance of it, and how comprehension of this educational technique may help develop more persuasive arguments that put the Hispanic population at the heart of contemporary society rather than on the outskirts of it
The Close AGN Reference Survey (CARS): IFU Survey Data and the BH Mass Dependence of Long-term AGN Variability
Get PDFContext. Active galactic nuclei (AGN) are thought to be intimately connected with their host galaxies through feeding and feedback processes. A strong coupling is predicted and supported by cosmological simulations of galaxy formation, but the details of the physical mechanisms are still observationally unconstrained.
Aims. Galaxies are complex systems of stars and a multiphase interstellar medium (ISM). A spatially resolved multiwavelength survey is required to map the interaction of AGN with their host galaxies on different spatial scales and different phases of the ISM. The goal of the Close AGN Reference Survey (CARS) is to obtain the necessary spatially resolved multiwavelength observations for an unbiased sample of local unobscured luminous AGN.
Methods. We present the overall CARS survey design and the associated wide-field optical integral-field unit (IFU) spectroscopy for all 41 CARS targets at z \u3c 0.06 randomly selected from the Hamburg/ESO survey of luminous unobscured AGN. This data set provides the backbone of the CARS survey and allows us to characterize host galaxy morphologies, AGN parameters, precise systemic redshifts, and ionized gas distributions including excitation conditions, kinematics, and metallicities in unprecedented detail.
Results. We focus our study on the size of the extended narrow-line region (ENLR) which has been traditionally connected to AGN luminosity. Given the large scatter in the ENLR size–luminosity relation, we performed a large parameter search to identify potentially more fundamental relations. Remarkably, we identified the strongest correlation between the maximum projected ENLR size and the black hole mass, consistent with an RENLR,max ∼ MBH0.5 relationship. We interpret the maximum ENLR size as a timescale indicator of a single black hole (BH) radiative-efficient accretion episode for which we inferred 〈log(tAGN/[yr])〉 = (0.45 ± 0.08)log(MBH/[M⊙]) + 1.78−0.67+0.54 using forward modeling. The extrapolation of our inferred relation toward higher BH masses is consistent with an independent lifetime estimate from the He II proximity zones around luminous AGN at z ∼ 3.
Conclusions. While our proposed link between the BH mass and AGN lifetime might be a secondary correlation itself or impacted by unknown biases, it has a few relevant implications if confirmed. For example, the famous AGN Eigenvector 1 parameter space may be partially explained by the range in AGN lifetimes. Also, the lack of observational evidence for negative AGN feedback on star formation can be explained by such timescale effects. Further observational tests are required to confirm or rule out our BH mass dependent AGN lifetime hypothesis
