description: MCG-03-34-64 is a nearby Seyfert galaxy with extremely heavy X-ray absorption that makes it one of the hardest sources in the X-ray sky. Consequently this is a superb candidate for study of the faint comma  extended comma  circumnuclear X-ray emission. Chandra imaging results for other nearby Compton-thick AGN show structure on a scale of hundreds of pc coincident with the Narrow Line Region gas. Following on from those successful observations we request a 50 ks ACIS-S exposure to trace out the line emitting regions in MCG-03-34-64. We also ask for an HST orbit to map CORCHETE_OPENOiiiCORCHETE_CLOSE for comparison with the X-ray extent.

description: Is the neutral ISM in the Galaxy clumpyquestionMark Does pristine gas infalling on the disk immediately mix with the metal-enriched gasquestionMark Recent medium-resolution STIS studies found frequent sub-solar metallicities in the neutral ISM comma  integrated along the line of sight comma  suggesting the contribution of low-metallicity gas. Intriguingly comma  in some cases deviations from the expected depletion patterns were observed for volatile elements. One possible explanation for both effects is a mix between metal-dust-rich and pristine gas (low metallicity and zero depletion) in the ISM. Indeed comma  an inhomogeneous ISM mix has been recently observed in high-resolution STIS observations of HD 62542. Here we propose to target 8 lines of sight that show potential contribution of pristine gas in the following waysdoublePoint 1) low metallicity integrated along the line of sight comma  2) deviations in the depletion of the volatile elements comma  and 3) complex-asymmetric kinematics comma  as measured from lower-resolution studies. The STIS high-resolution will enable a component-by-component analysis to characterize the depletion properties of individual clumps. Our primary goal is to constrain dust-rich and dust-free ISM clumps towards our targets. In addition comma  we aim at roughly constraining the metallicity of these ISM clumps by exploring the parameter space that can reproduce the observed deviations of the volatile elements. This way we will characterize the inhomogeneities in the ISM and unveil the potential presence of clumps of pristine gas. While chemical evolution models show that infalling pristine gas is necessary to sustain star formation and reproduce the observed abundances comma  its presence in the ISM is yet to be confirmed.

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.

description: This proposal will acquire absolute gain data for every quadrant (A comma  B comma  C comma  and D) of the WFC3-UVIS detector to continue monitoring the gain stability. This has been a recurring CAL program since Cycle 17 and allows us to measure both long and short term gain stability. We will continue to take both un-binned and binned (2x2 and 3x3) gain measurements.

description: Since the discovery of globular cluster LMXBs in the 1970s comma  it was long assumed there was only one luminous LMXB per cluster. Deep Chandra observations of globular clusters have revealed that they contain numerous quiescent LMXB systems comma  any of which could go into outburst. Our past Chandra programs have shown that globular clusters can indeed harbor multiple transients and that more quiescent LMXBs are hiding under the sensitivity limits of even relatively deep Chandra exposures. Here we propose to continue our Chandra program to precisely localize new transients in globular clusters comma  with the aim of gaining better insight into globular cluster LMXB populations. As part of this effort we further request HST observations to identify the optical counterparts of these transients.

description: We have detected a strongly lensed supernova (SN) in HST imaging of the RX J2129 galaxy-cluster field acquired on August 7 comma  2022.  The SN.s apparent F110W magnitude of 24.70+-0.15 and a non-detection in F606W yield an 80% probability that the transient is a Type Ia SN.  The foreground galaxy-cluster gravitational lens creates a set of three images of the SN.s host galaxy at redshift 1.52 comma  and we have detected the SN in the trailing comma  or last-arriving image. The other images are predicted to have arrived virgul320 and virgul1000 days previously.  A target-of-opportunity program with HST has been triggered to measure the transient.s light curve through late October. Here we propose three single-orbit WFC3 IR F110W-F160W  visits followed by a two-orbit visit to measure the SN.s light curve through late December. In a joint proposal comma  we request NIRSpec G140M and PRISM spectroscopy at the locations of all three images in early October comma  when the field becomes accessible to JWST. If the SN is a Type Ia SN comma  then we will be able to calibrate its luminosity and directly measure its magnification. This will provide a novel test of galaxy-cluster mass models. The spectra will enable comparision with low-redshift SNe Ia to address an important systematic that may affect SN Ia cosmology.   We also propose for deep JWST NIRCam imaging to measure the flux of the previous arrival of the SN. With 5-sigma limiting depth of 29.2 comma  imaging in F150W can be expected to detect the fading image. Its brightness will constrain the SN.s age comma  and therefore the image.s relative time delay.   A strong detection and well-characterized SN Ia may enable a new comma  independent measurement of the Hubble constant.

description: Recently comma  the TESS spacecraft uncovered an exciting three-planet system that included its first habitable zone terrestrial planet comma  TOI-700 d. This system orbits an M2V dwarf located 31 pc away from Earth. Previous studies of the TOI-700 system have not included photochemistry comma  but photochemistry can strongly impact planetary atmospheric composition comma  habitability comma  and observable spectral features. A critical input for accurate photochemical modeling of this system is the UV spectrum of the host star comma  TOI-700. Measured UV spectra of exoplanet host stars have been heavily used for a diverse range of modeling efforts and are a critical in-demand need of the exoplanet community. We will measure the UV spectrum of TOI-700 (1150-5000 A) comma  use it to update previous modeling efforts of possible atmospheres and spectra of TOI-700 d comma  and make the spectrum available to the community. This will result in the first self-consistent model atmospheres for TOI-700 d using a 3-D climate model with clouds and atmospheric dynamics coupled to a photochemical and spectral model. We will be able to put this new analysis into the context of previous works considering climatically and photochemically self-consistent atmospheres and spectra of potentially habitable M dwarf planets. TOI-700 will be the earliest M dwarf for which such a study has been performed for a specific known planet and will thus provide a useful point of comparison against potentially habitable worlds around later M dwarfs comma  including TRAPPIST-1 (M8V). The stellar UV spectrum we measure will also be able to be used in future works considering the atmospheres and spectral features of all planets in the TOI-700 system.

description: We wish to use the STIS and WFC3-IR modes of HST to carry out spectroscopic observations of two NIRISS commissioning targets from roughly 0.5 to 1.7 microns to establish the spectra shape of one target and the spectral shape and (approximate) absolute calibration of the second target.  The spectra will be used in the analysis of the NIRISS commissioning programs NIS-018 (APT 1092) and NIS-034 (APT 1541).  Although these observations will cover only about half the spectral range of the NIRISS GR700XD grism comma  it will provide the only available check on the quality of the NIRISS commissioning calibration products in this mode.

description: We propose an HST-COS spectroscopy of 8 QSOs probing the extended major axis region of a sample of purely edge-on galaxies.  Several studies probing these major axis CGM regions have shown that low-ionization absorption (Mg II) is kinematically correlated with the disk rotation comma  a potential signature of gas accretion fueling star formation and adding angular momentum to the disk.  However comma  similar results for high-ionization material (O VI) show that the O VI absorption is not kinematically correlated with the disk rotation and likely traces the ambient comma  volume-filling hotter halo phase. Our study will be the first to simultaneously characterize the phase structure of these accreting streams via absorption from low- and intermediate-ionization species.  We have a ground-based spectroscopic program underway to measure the rotation curves of all of our galaxy targets as well as spatially resolved SFRs and metallicities.  We will correlate the kinematics of the detected CGM absorption in these COS data comma  including Si II comma  Si III comma  Si IV comma  C IV comma  and H I Ly-alpha with the galaxy rotation curves as well as the SFR-metallicities in the disk.  In addition to unprecedented constraints on mid-ionization phases comma  our study will be the first to leverage truly edge-on galaxies in such an analysis comma  eliminating uncertainties associated with the galaxy inclination.

description: AbstractdoublePoint We propose a HST near-IR + SOFIA far-IR study of NGC 2071 comma  a system of at least two outflows from a small group of intermediate to low luminosity stars. Protostellar outflows are ubiquitous part of the star formation process. They provide a record of variable accretion onto stars comma  have significant impact on the surrounding molecular cloud comma  and may disrupt or trigger star formation in molecular clouds. Intermediate-luminosity (30 < Lbol < 1000 solar luminosities) protostars bridge the gap between low- and high-mass star formation comma  forming stars with masses between 2 and 10 solar masses (Di Francesco et al. 1997  Mannings  and  Sargent 2000). Outflows from these systems of protostars have a significant impact on the surrounding ISM comma  may play an important role in cloud evolution comma  and are an important laboratory for understanding the origin of far-IR line emission from outflows. In this study comma  WFC3-IR images of CORCHETE_OPENFeIICORCHETE_CLOSE and Paschen Beta lines will trace J-type shocks in the near-IR. Proper motions of knots will be derived from a 2009 WFC3-IR image. SOFIA 4GREAT will trace emission from far-IR transitions of CORCHETE_OPENOICORCHETE_CLOSE and four additional CO transitions tracing shock heated gas. These lines will provide both radial velocities of the shocked emission as well as measurements of the mass flow and heating by shocks and UV radiation. The combined data will provide 3D space motions of the knots of shock accelerated gas where the outflow is interacting with the surrounding molecular cloud. Additionally comma  shock  velocities and mass and energy momentum flows through the shocks will provide one of the most detailed measurements of the feedback from a system of protostars to date.

description: Recently it was discovered that the change in home position of the OSM1 mechanism to G130M-1222 was causing systematically low dispersion direction placements of the G130M-1291 mode spectrum on the detector comma  causing additional gain sag holes due to geocoronal Lyman alpha. After investigation comma  this behavior comma  as well as a systematic trend in higher dispersion direction spectrum placement for G130M-1222 FP-POS=2 comma 4 resulted in the decision to change home positions. Since the behavior observed is correlated with home position comma  this program was designed to monitor the switch to a) verify that these behaviors are mitigated and b) if not mitigated comma  clearly understand what is causing the trends-issues.

description: The Space Telescope Science Institute (STScI) Director has decided to devote up to 1000 orbits of Director.s Discretionary time in observing Cycles 27-29 to a new Hubble Ultraviolet Legacy program focused on star formation and associated stellar physics. This new program comma  ULLYSES (UV Legacy Library of Young Stars as Essential Standards) comma  will provide a UV spectroscopic reference sample of young (< 10 Myr) high- and low-mass stars. It will target virgul165 OB stars in the Magellanic Clouds and lower metallicity galaxies in the Local Group comma  and virgul67 T Tauri stars and brown dwarfs in the Milky Way. In addition comma  ULLYSES will monitor 4 typical T Tauri stars over different rotational phases through at least three rotation periods comma  and over timescales of months to years. The resulting library will provide template spectra of massive stars at metallicities substantially below the well studied comma  while the low mass sample will cover a wide range of ages comma  accretion rates comma  and masses comma  including objects down to well below 0.5 M_sun. The legacy of this large UV dataset on the first 10 Myr of stellar evolution will be enhanced by complementary datasets obtained by the scientific community. In addition to the core goals of the program related to stellar astrophysics of low and high mass stars comma  this data will also enable exciting science in the fields of ISM comma  CGM comma  jets comma  and exoplanets. ULLYSES will be modeled after the Frontier Fields programdoublePoint all data obtained will be non-proprietary. The implementation team at STScI is developing high-level science data products and a sophisticated database and website for disseminating data from the ULLYSES program and ancillary datasets for the ULLYSES target sample from space and ground-based facilities.
