0 Assigned ID: 4036 ----- Attempting Submission 1 (Mon May 22 18:11:40 GMT 2023) ----- Thank you for your assistance in verifying the suitability of our setup. 1. For COS/FUV, we are using all four FP-POS to obtain the spectra. According to our understanding, despite positional offsets between these locations, our target objects will still remain centered within the slit. Is this understanding is correct? 2. During the execution of BOT, we have encountered two COS acquisition visits that are displaying a red "Health/Safety" status. It has come to our attention that both of these visits may have bright stars present in the field. Additionally, we have received ERROR messages from STIS/CCD in BOT. We would appreciate your guidance on whether these observations warrant any specific concerns. 2036328325 ----- Attempting Submission 1 (Fri Sep 08 19:55:44 GMT 2023) ----- HST UV Spectroscopy of High-accretion-rate AGNs and the Origin of Offset in the Broad-Line Region Size-Luminosity Relation Nearly two decades of reverberation mapping (RM) studies on local broad-line AGNs have revealed a tight correlation between the broad-line region (BLR) size and the AGN optical luminosity (the R-L relation), which provides the foundation for single-epoch virial black hole mass recipes that estimate AGN black hole masses using single-epoch spectra. However, recent RM studies for AGNs with a more diverse range of accretion parameters revealed an increased dispersion around the canonical R-L relation. In particular, high-accretion-rate (e.g., L/LEdd>0.5) AGNs show a significant lag offset by a factor of 3-4 at fixed optical luminosities. Understanding the origin of this dispersion/offset in the R-L relation is critically important for single-epoch mass recipes. One promising explanation for this dispersion/offset is that the underlying ionizing spectral energy distributions (SEDs) are different at different accretion rates. Here we propose HST UV spectroscopy for 16 high-accretion AGNs at 0.05<z<0.7 with RM measurements to test this hypothesis and to develop empirical corrections to tighten up the R-L relation. We will measure the rest-frame UV emission-line properties, and perform detailed photoionization calculations to constrain accretion disk models and SED predictions. The comparison of photoionization calculations and observed spectra for a unique high-accretion AGN sample would not only facilitate a better theoretical understanding of high-accretion disk models (e.g., the slim disk model), but also shed light on the physical driver of the R-L relation dispersion and enable better calibrations of single-epoch mass recipes. We have selected a sample of 16 low-redshift (0.05<z<0.7) high-accretion AGNs with GALEX NUV mag < 21 in this proposal. For 8 targets at z < 0.2, we choose the HST COS/FUV in spectroscopic mode with the G140L grating and a central wavelength of 1280 A. Firstly, the NUV ACQ/IMAGE MirrorB is used for target acquisition to meet the safety limits. We calculate the acquisition exposure times with the ETC for a minimum SNR of 20 for PSA mode, assuming a point-like source. Then each FUV exposure will fit in the same orbit as the target acquisition and use all four FP-POS positions to obtain the spectra with SNR~10 per resolution element. The BUFFER-TIME is set to be 2/3xBFT as recommended by the handbook. For 8 targets at z > 0.2, we choose HST STIS/NUV-MAMA in spectroscopic mode with the G230L grating to optimize the need for spectral coverage. We will use the point-source mode and F28x50LP CCD aperture for target acquisition, and the acquisition exposure time is computed from ETC to obtain an SNR of at least 40. Then we will take one or two (depending on the orbit, 1 for 5 targets, 2 for 3 targets) MAMA exposures to reach SNR~10 per resolution element, where 52" x 0.2" slit is used and BUFFER-TIME is set to be 300s. The proposing team includes experts on reverberation mapping (RM), AGN physics, and photoionization modeling. Team memebers have access to the multi-wavelength data already collected for the target sample. Specifically, Co-PI Shen works on RM and AGN science, and is leading the SDSS-RM project and its extension into the SDSS-V survey (2020-2025). PI Qiaoya Wu is a PhD student at Co-PI's institution working on the SDSS-RM data and photoionization.
