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: The massive red supergiant Antares (alpha Sco AdoublePoint M1 Iab) is an excellent star to test theoretical models of mass loss because its distance comma  age comma  stellar parameters comma  mass-loss rate comma  and interstellar reddening are well established. The early-M supergiants pose a particular challenge for models of mass loss driven by radiation pressure on molecules and-or dustdoublePoint The circumstellar molecular abundances and dust-to-gas mass ratios are lower than for later-M spectral-types comma  but they still manage to drive massive winds.  We request deep FUV and NUV observations to perform an extremely sensitive test for the most robust circumstellar molecule comma  CO comma  by observing its Fourth-Positive electronic bands against the FUV continuum  of the M supergiant Antares. These observations will enable us measure any CO present in the outflow comma  and to place upper-limits on the effective radiation acceleration it can provide. The proposed observations will also provide an invaluable dataset for Antares comma  the oft neglected southern twin of Betelgeuse comma  and our nearest Type II supernova progenitor.

description: Low-metallicity massive stars may have reionized the universe at z > 6. Yet comma  their contribution to the ionizing photon budget remains unconstrained and can only be estimated from stellar models. The predicted ionizing flux is highly sensitive to theoretical mass-loss rates and metal opacities comma  but these have never been observationally determined below the metallicity of the SMC (20% solar). Observations of individually resolved comma  metal-poor O stars spanning a range of masses and evolutionary stages are needed to determine the contribution of high-redshift galaxies to cosmic reionization.  Sextans A is the only nearby dwarf galaxy substantially more metal-poor than the SMC that hosts more than a few known O stars. Five have already been observed by COS and two more will be observed by ULLYSES comma  but these do not sample the full range of spectral types and luminosity classes. We propose new G130M and G160M COS observations of two late-O (super)giants that sample new parameter space. For the first time at 6% solar metallicity comma  the combined new and archival COS data will enable us to (1) empirically determine the photospheric metal opacities that set ionizing photon production  (2) measure mass-loss rates as a function of spectral type to improve the purely theoretical mass-loss prescriptions that underlie stellar evolution models  and (3) produce new stellar spectral templates tailored to the FUV observations that will be ideally suited to modeling the ionizing spectra of galaxies during the epoch of reionization. The proposed observations are urgently needed to interpret upcoming JWST campaigns at high redshift and can only be done with HST-COS.

description: Obscuring outflows are remarkably different from the warm-absorber outflows in AGN. They exhibit large columns of high-velocity gas close to the accretion disk. They shield the X-ray radiation comma  which has important implications for the launching of outflows. They were first discovered in NGC 5548 thanks to simultaneous X-ray and UV observations in 2013. Recent Swift monitoring of NGC 5548 points to remarkable long-term changes in the strength of X-ray obscuration in NGC 5548. In order to study this change comma  simultaneous X-ray and UV high-resolution spectroscopy is required. Therefore comma  we propose simultaneous Chandra-HETG (150 ks) and HST-COS (2 orbits) observations to help us address existing questions about the origin and physical structure of the long-lasting obscuration in NGC 5548.

description: The solar analog star HD 53143 hosts a tenuous disk of cold material analogous to a more massive version of our solar system.s Kuiper Belt. Puzzlingly comma  unlike every other debris disk observed thus far comma  existing low-S-N visible wavelength images of HD 53143 show that the micron-sized dust around HD 53143 does not resemble a circumstellar ring--rather comma  it looks like two isolated clumps of material. New ALMA observations show that the underlying distribution of larger planetesimals is indeed ring-like comma  but very eccentric and mis-aligned with the visible wavelength clumps. Further comma  the ALMA observations reveal 5-sigma excesses just interior to the circumstellar ring comma  suggesting structure in the planetesimal population that may be connected to the visible wavelength clumps. We propose high-S-N coronagraphic imaging of HD 53143 using HST STIS to reveal the peculiar nature of this unique debris disk and search for signs of planet-induced disk structure or collisional activity. In addition to revealing the structure of the disk comma  these high-S-N images will allow us to measure the optical properties of the debris disk dust to constrain its composition comma  size distribution comma  and provide critical measurements of debris disk properties that will inform future exoplanet-imaging missions.

description: This program obtains COS FUV lamp template data at LP5 and LP3 for the wavelength calibration of LP5 and LP3 data. The dispersion coefficients vary with absolute focus position comma  and since the lamp template reference file currently in use for wavelength calibration was obtained at LP4 with a different absolute focus than that used for LP5-LP3 observations comma  we want to update the lamp template data for LP5-LP3.

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.

description: We propose to acquire HST-WFC3 imaging of two galaxies at zvirgul7 recently detected by ALMA in CORCHETE_OPENCIICORCHETE_CLOSE 158 micron and CORCHETE_OPENOIIICORCHETE_CLOSE 88 micron emission at high angular resolution. The CORCHETE_OPENOIIICORCHETE_CLOSE emission comma  corresponding to diffuse comma  highly-ionized gas comma  and CORCHETE_OPENCIICORCHETE_CLOSE emission comma  tracing neutral gas comma  allow some of the first explorations of the interstellar medium in the Epoch of Reionization (EoR). Combined comma  they suggest we are witnessing intense star formation which locally shows extreme CORCHETE_OPENOIIICORCHETE_CLOSE-CORCHETE_OPENCIICORCHETE_CLOSE luminosity ratios that are indicative of .leaking. ionizing radiation and hence may be of great importance to Reionization. Other regions in these galaxies comma  however comma  might be more metal-enriched and obscured by dust comma  as indicated by ALMA measurements of the dust continuum. To conclusively shed light on the key processes affecting star formation in the EoR comma  we propose to obtain deep HST images of the rest-frame UV (both a virgul5x improvement in limiting flux and angular resolution over existing comma  ground-based imaging). We will measure accurate sizes of star-forming clumps on sub-kiloparsec scales comma  study possible ongoing mergers comma  and compare the UV morphology with spatially resolved maps of dust continuum and physical parameters such as the ionization parameter extracted from the CORCHETE_OPENCIICORCHETE_CLOSE and CORCHETE_OPENOIIICORCHETE_CLOSE observations. These comparisons will give insight into the physical conditions of both UV-bright star-forming clumps and dust-obscured star-forming regions. Combined with a larger sample including three other galaxies comma  this data will paint a physically motivated picture of star formation in the EoR in time for science exploration with JWST.

description: This program uses the deuterium lamp to illuminate the regions of the detector being used to collect spectra during Cycle 28. The data obtained will be used to create gain maps of the detector. Because of the strongly varying intensity of the lamp as a function of wavelength comma  G130M-1309 data will be obtained for Segment A comma  and G160M-1600 will be used for Segment B.  Gain map data will be obtained at virgul6 month intervals for modes where the voltage is unchanged. Obtaining a gain map at these times will help to improve the modeling of the modal gain as a function of time and extracted charge comma  since it will provide data that cover the full time span of each high voltage at each LP. Improving these models will allow better predictions of the future lifetime of the detector.

description: The nearest and most well-studied Lyman continuum (LyC) emitting galaxy comma  Haro 11 comma  offers an unparalleled opportunity to determine the conditions for LyC escape at 15-pc resolution.  However comma  we do not know which of the 3 dominant star-forming knots is the LyC sourcedoublePoint  Knot C is a strong Ly-alpha emitter (LAE) with an ultraluminous X-ray source (ULX)  Knot B hosts a very luminous ULX that is a candidate low-luminosity AGN (LLAGN)  and Knot A is a starburst driving optically thin comma  Green Pea-like properties. Our proposed COS spectra of the LyC will identify which of the three knots is responsible for the known LyC emission.  Depending on which Knot is confirmed as the LyC emitter (LCE) comma  it would illuminate the connection between LyC escape anddoublePoint  LAEs and ULXs (Knot C)  ULXs-LLAGN (Knot B)  or Green Peas (Knot A).  If Knot C is not confirmed comma  then this would overturn the widely held paradigm that all LCEs must be strong LAEs.  If Knot B or C is the LyC source comma  then this first confirmation of a ULX LCE would imply that black hole accretion processes in dwarf galaxies may be a viable cosmological source of LyC.  By establishing the LyC source in this iconic galaxy comma  these observations will allow much-needed comma  spatially resolved comma  detailed study of the radiative transfer of LyC from the ionizing source through the local ISM. Our results will clarify understanding of LyC escape and its relation to Ly-alpha comma  and inform efforts to identify LCEs at higher redshift.

description: While we have long known that jets from super-massive black holes exhibit highly relativistic speeds on parsec scales from radio interferometry comma  it is not generally known how the jet evolves on kpc to Mpc scales comma  where the jet leaves the host galaxy and begins to interact with the intergalactic medium comma  with implications for our understanding of jet structure and quantifying the energy carried by the jet into the external environment. With the development of state-of-the-art astrometry techniques and new data from the Gaia mission comma  it is now possible register images of nearby jets first observed by HST in the 1990s to extremely high precision comma  reaching accuracies on proper motions of better than 0.3 mas-year. This enabled the dramatic finding of colliding superluminal knots in the jet of 3C264 and helical motions of plasma on kpc scales in M87. We propose a new epoch on the 7 remaining nearby optical jets which have been previously observed by HST for proper motions. This sample is an extremely unique one comma  and only HST can provide the precision astrometry and sensitivity needed to track the motion of plasma in jets on kpc scales.
