description: The HST-TESS Exoplanet Initiative (HTEI) was recently recommended by STScI to capitalize on the wealth of nearby sub-Neptunes discovered by the Transiting Exoplanet Survey Satellite (TESS). Even though sub-Neptunes are very common comma  there are still major open questions about how they form and evolve. Direct measurements of their atmospheric composition are a powerful tool to distinguish between different formation models. Fortunately comma  the abundance of new TESS discoveries provides an opportunity to systematically study sub-Neptune atmospheres for the first time. Here we propose a community-driven HTEI ProgramdoublePoint SPACE (the Sub-neptune Planetary Atmosphere Characterization Experiment).  The SPACE Program will combine UV stellar characterization with WFC3 transmission spectroscopy for eight sub-Neptune systems.   The targets span a physically-motivated grid across planet radius (2 - 3.5 Re) and temperature (300 - 1400 K) comma  specifically designed to reveal how sub-Neptune atmospheres are shaped by UV photochemistry comma  equilibrium cloud formation comma  atmospheric metal enrichment comma  vertical mixing comma  and photoevaporation.  The UV spectra are urgently needed because they are a crucial input for photochemistry and atmospheric escape models comma  and can only be obtained while HST is still operational.   With these measurements comma  SPACE will extend HST.s exoplanet legacy from hot Jupiters to the much more abundant sub-Neptunes comma  to rapidly establish demographic trends  and identify cloud-free atmospheres for future follow-up of this exciting population.

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: A recently discovered z = 5.04 lensed galaxy comma  COOLJ1241+2219 comma  has an AB magnitude z = 20.5 comma  making it is the brightest known z > 5 galaxy at OIR wavelengths by a factor of five. It is lensed by a galaxy cluster with spectroscopic z = 1.002 comma  and a preliminary lens model indicates that the mass of that cluster core is virgul10elev14 solar masses. The observed rest-wavelength UV of the lensed galaxy indicates formation of massive stars in the recent past comma  yet an upper limit of 2 mJy-beam at 314 GHz from the SMA indicates there is little dust in a warm neutral medium. It is not comma  therefore comma  one of the usual SMG detected by millimeter-wave and FIR surveys comma  it is something newdoublePoint a galaxy in the early Universe where star formation is already in decline. We propose a first look of this source in the radio at the high end of the VLA Ka band comma  which includes the CO J=2-1 line comma  for three 4-hour sessions that should detect the galaxy.s remaining star-forming molecular material. A three-orbit joint request to HST will provide data to refine the lens model and allow inversion of the lens to reconstruct the unlensed galaxy.

description: This program monitors the sensitivity of three NUV gratings to detect any changes due to contamination or other causes. Observations execute twice a year (in approximately February and August). Beginning in Cycle 24 comma  additional cenwaves were added for the medium-resolution gratings (G185M-2010 comma  G285M-2850 comma  G225M-2306 comma  and G225M-2410). Beginning in Cycle 26 comma  monitoring of G285M was discontinued due to its low sensitivity and lack of usage over the past few HST cycles. Given these considerations comma  the user community is urged to use STIS instead. If for any reason there is a need to use COS-G285M comma  the monitoring of this mode will be reinstated.

description: We propose HST mid-cycle imaging of the host galaxy of a fast radio burst (FRB) localized to milliarcsecond precision to constrain the origin of this enigmatic comma  highly active comma  repeating burst.  Recent publications  (based on HST observations) have established that FRBs occur primarily in star-forming galaxies with galactocentric offsets ranging from virgul1 to 10 kpc.  These data also indicate a high incidence of spiral arm structure in the near-IR band and suggest the frequent appearance of FRBs within these arms.  With deep WFC3-UVIS 475X images we will observe the host of FRB 20201124A to precisely measure its spiral arm structure and to add to the quantitative assessment of the distribution of FRB progenitor locations relative to the arms.  Following similar studies on other transients (e.g. supernovae) comma  our experiment will yield new constraints on FRB progenitor channels by establishing the relationship of FRBs to recent star-formation and their progenitor lifetimes comma  using the high-resolution HST imaging in conjunction with VLA imaging of radio emission (presumed associated to recent star formation). The proposed observations with deep HST-WFC3 F160W will also determine the morphology comma  galactocentric offset comma  radial light distribution and local measure of the  stellar mass surface density. The observations will utilize HST.s high angular resolution imaging and UV sensitivity to measure the immediate galactic environment of this FRB and the nature of star formation to within a single pixel (0.1 kpc) of the burst.s origin. We commit to rapid publication and release of the data to guide future research of this unique source.

description: Physical processes governing the formation-evolution of high-redshift galaxies in the epoch of reionization (EoR  z>6) are still not well understood.  In most cases comma  EoR galaxies are fuzzy faint blobs showing little internal structure comma  and fitting various theoretical models to spatially-integrated spectral energy distributions (SEDs) is often all that can be done.  There are comma  however comma  a small number of luminous EoR galaxies comma  such as Himiko at z=6.595 and CR7 at z=6.601 comma  whose exceptional brightnesses have allowed spatially-resolved studies and have revealed some fascinating details.  Although such luminous EoR galaxies are rare comma  the Subary-Hyper Suprime-Cam (HSC) survey has recently discovered 7 comparably bright EoR galaxies with y < 25 mag (in comparison comma  y=25.4 and 24.5 mag with Himiko and CR7 comma  respectively).  Here comma  we propose to obtain HST-WFC3 near-infrared images for these exceptionally luminous z>6 galaxies with the F105W comma  F125W comma  and F160W filters.  Our goals are comma  (1) to identify the rest-frame UV continuum morphology comma  (2) to measure UV continuum spectral slopes comma  and (3) to compare the UV continuum morphology with those of Ly-alpha comma  CORCHETE_OPENC IICORCHETE_CLOSE comma  and dust emission when possible.  The obtained HST data will allow us to probe the internal structures and underlying physical processes in these remarkable high-redshift galaxies.  The targeted z>6 EoR galaxies are so bright that they will also make excellent targets for NIRSpec IFU observations comma  enabling us to study the internal structure and kinematics of these high-redshift galaxies in greater detail.  The obtained HST data will also be essential to make effective us of precious JWST time.

description: The newborn planetary system comprising of four gas giants transiting the bright 23 Myr old star V1298 Tau presents an exciting opportunity to probe the atmospheric properties of planetary systems immediately post-formation comma  and to do so within one system. We propose to observe a transit of the hottest gas giant in the system comma  V1298 Tau c comma  using the HST-WFC3-G141 grism comma  to measure the strength of water absorption features. The NIR transmission spectrum of this hot Neptune planet will be used to constrain its metallicity and cloud or haze coverage comma  which in turns will inform planet formation and evolution models. In conjunction with the previous WFC3-G141 observations of the warm gas giant V1298 Tau b in the system comma  our observations will enable comparative exoplanetology of planets within a multiplanet system fresh after formation. When put in the context of directly imaged planets at wider orbital separations but similar age as the V1298 Tau system comma  the inferences from our comparative study of a close-in multiplanet system will put constraints on the effect of insolation and location in the planet-forming disks on the bulk planetary composition and properties.

description: The Cold Classical Transneptunian objects (TNOs) are one of the least processed solar system subpopulations comma  making them a perfect place to test planet formation hypotheses. One of the most favored planetary formation models is the streaming instability comma  which predicts that binaries should be extremely common comma  especially among the Cold Classical. It also predicts that the spins of individual binary components will be well aligned with the binary orbit. Unfortunately comma  to date comma  this prediction has been difficult to test comma  but with increasingly long observational baselines comma  non-Keplerian orbital analysis is able to precisely measure both the shapes and spin poles of individual binary components. With these measurements comma  a quantitative test of the streaming instability model of planetesimal formation can be completed. In this program comma  we request 8 orbits to precisely measure the spin poles and shapes of Cold Classical TNOs comma  which will enable a detailed test of planet formation models.

description: The recently discovered galaxy BST 1047+1156 is the most diffuse star-forming galaxy found to date. Located in the Leo I galaxy group (D=11 Mpc) comma  its extremely diffuse nature tests models of both galaxy formation and star formation at the lowest densities. BST1047.s extraordinarily blue optical colors and UV emission both signal a recent episode of star formation in the object comma  even though its HI column density is well below that in which star formation typically occurs. Exactly how BST1047 formed remains uncleardoublePoint it may be either a long-lived but extremely diffuse LSB galaxy caught in a tidal interaction comma  or a recently spawned tidal dwarf caught in the throes of disruption. Either scenario places BST1047 at the extreme limits of our understanding of galaxy evolution processes.  To resolve the question of BST1047.s origins comma  we propose deep F606W-F814W imaging to construct a color magnitude diagram of its resolved stellar population and constrain the ages and metallicities of its stars. This will cleanly differentiate between the two formation scenarios comma  as the presence of old red giant branch stars would rule out the young tidal dwarf model. A purely young stellar population would mark BST1047 as a disrupting tidal dwarf comma  the first such object known comma  providing a new link between tidal interactions and dwarf galaxy formation and disruption. We will also place BST1047 on the well-determined stellar mass-metallicity relationship for normal star forming galaxies comma  providing another important test of its origins. Finally comma  we will use the  BST1047.s populations to probe the spatial distribution of recent and past star formation in this anomolous object.

description: Recently ACS-WFC geometric distortion have been assessed w.r.t standard astrometric catalog significantly improved with the access to globally accurate positions from the Gaia DR2 as it discussed by Kozhurina-Platais (ACS-ISR-2018-02). A newly derived and improved IDCTAB have been also converted into HST V2V3 system with improved SIAF of ACS-WFC w.r.t Gaia DR2 (J. Sahlmann TEL-ISR-2019). This IDCTAB has been tested using the 47Tuc observations over 20 years with the access to globally accurate positions from the Gaia DR2. The results of test have shown the significant improvement in the global astrometric accuracy of ACS-WFC compare to ICRS based on Gaia now (S. Hoffman comma  ACS_ISR-2020).  The results of this test have also shown that around 2017 Xscale  and  Yskew (linear terms of distortion) in both WFC CCD chips suddenly changed introducing errors at the far edges of ACS-WFC images by <0.2 pixels.  The galactic globular cluster 47Tuc (NGC104) 47Tuc has been used to examine the geometric distortion of ACS-WFC in multicycle calibration programs over last 20 years of ACS on HST board. Traditional ACS-WFC multi-cycle calibration program observing 47Tuc d_commaACS CCD Stability Monitord_comma consists of 4 HST orbits comma  repeated observations in F606W and wide pass-band ACS-WFC filter 2 x times a year.  This is too sparse observations to keep track on the time-depended scale and skew variations comma  as indicated by their pattern since 2017. In order to secure an accurate calibration of these two indirect terms (Xscale  and  Yskew) comma  we request additional 3 HST orbits well-spread over a year of Cyc 28 to observe 47 Tuc through F606W.

description: The FUV gratings are the most used modes on COS.  They have experienced changes in sensitivity since the instrument was installed.  The trends in the time-dependent spectroscopic sensitivity depend on the grating comma  segment and wavelength.  This calibration proposal is to monitor the sensitivity of each FUV grating mode at several cenwave settings on an approximately bi-monthly schedule comma  and to characterize the observed trends.

description: Space-based observations are on the cusp of a near-infrared (NIR) revolution comma  with the imminent launch of the Webb telescope comma  and the planned launch of the Roman (formerly WFIRST) telescope. This program aims to bridge the gap between the current and coming eras by simultaneously providing (1) the most accurate zero-point calibration of the Tip of the Red Giant Branch (TRGB) in the ACS-WFC F606W and F814W bands to date comma  and (2) the first direct comma  geometric calibration of the TRGB zero-point in space-based near-infrared (NIR) bandpasses (all previous calibrations were indirectly calibrated). We will accomplish this in only 16 orbits comma  a small fraction of the HST time already invested into comparable calibrations (e.g. comma  over 150 orbits dedicated to calibrating Cepheids in this galaxy) comma  and at a much higher accuracy.

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 over virgul150 OB stars in the Magellanic Clouds and lower metallicity galaxies in the Local Group comma  and virgul40 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.
