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: Active Galactic Nuclei (AGN) are the observed manifestation of the inflow of matter onto supermassive black holes. Winds driven away from black holes have also been observed comma  which might play an important role in the evolution of black holes and their host galaxies. The obscuring wind is a rare breed of AGN winds comma  which has been observed in only a few Seyfert 1 galaxies so far. This putative disk wind absorbs a large fraction of the soft X-ray photons. Contemporaneous blueshifted broad absorption troughs associated with UV and NIR resonance lines appear in association with the emergence of the soft X-ray obscuration. Obscuring winds are expected to be present in quasars (more massive and luminous AGN) with broad absorption lines. The accelerated UV-absorbing gas needs to be shielded from much of the UV-X-ray ionizing radiation. Aside from the well-known properties of broad absorption line (BAL) QSOs comma  the transient appearance of obscuring winds in quasars with typically clear lines of sight has not been observed so far. Recent Swift X-ray data of the radio-quiet quasar MR 2251-178 suggest that the soft X-ray spectrum is significantly absorbed. Simultaneously comma  a blueshifted broad absorption trough of He I 1.08 micron is developing in recent high-resolution NIR spectra observed with IRTF and Gemini. We propose to observe MR 2251-178 with HST-COS (1 orbit) to constrain the physical properties of the putative obscuring wind and to explore similarities and differences with Seyfert galaxies like NGC 5548 and NGC 3783.

description: We propose to create a legacy map of the southern half of M31 in the optical and near ultraviolet (NUV).  The Panchromatic Hubble Andromeda Southern Treasury (PHAST) will add virgul100 million stars to M31.s stellar photometry archive and cover regions of M31 that are structurally unique and more sensitive to the merger history than the northern disk mapped in the Panchromatic Hubble Andromeda Treasury (PHAT).   These newly mapped regions include the intersections with M32 and the giant southern stream comma  the split portion of the star forming ring comma  and the southern bar.  By providing age comma  metallicity comma  stellar mass comma  and follow-up kinematics comma  the resolved stellar photometry of these regions will be used for detailed comparisons to simulations comma  including star formation history and population asymmetries as well as the orbits of M32 and the giant southern stream comma  allowing us to distinguish between competing merger scenarios.  Thus comma  these measurements tightly constrain models of M31.s merger history and disk evolution.  Furthermore comma  the legacy value for such observations is undeniable  M31 has been and will continue to be a centerpiece target for many NASA and ESA missions comma  as well as for ground-based time-domain observations that could find extremely valuable events that require HST resolution for identifying precursors.  These current and future data sets cover the entire galaxy comma  and thus comma  our coverage will increase the value of all past and future M31 observations.  PHAST will complete a lasting baseline data set for this high-demand target that no other current or planned facility will be able to produce.

description: This program verifies that FUV spectroscopic target acquisitions are working nominally for the modes allowed in cycle 29doublePoint G130M at LP5 comma  G140L at LP4 comma  and G160M at LP4. For each grating the cenwave with the widest cross dispersion profile in which acquisitions are done is used comma  yielding the combinations G130M-1291 comma  G140L-1280 comma  and G160M-1600. After the standard target WD 1657+343 is centered using ACQ-IMAGE we take spectra at the NUM-POS positions used by the PEAKXD and PEAKD algorithms to inspect those regions of the detector and check the vignetted flux. We then perform a PEAKXD and-or PEAKD acquisition and take a spectrum to verify centering. We test PEAKXD with NUM-POS=3 (default) and 5 comma  and PEAKD with NUM-POS=5 (default). A detailed description of the observations is given in the visit level comments. This program follows the prescription used in the last several cycles comma  and is most recently adapted from cycle 28 program 16326.

description: Direct Hubble constant measurements rely on a solid extragalactic distance scale comma  which is conventionally calibrated with Cepheids and recently the tip of the red giant branch (TRGB). As a different approach comma  Mira variables exhibit promising properties as independent distance indicators. Miras are luminous in the NIR comma  follow tight period-luminosity relations (PLRs) comma  and are present in all types of galaxies. Long-period Miras (400<P<1500 d) are much brighter and on steeper PLRs than the commonly used short-period Miras (100<P<400 d) comma  and they would potentially add a new route to check the Hubble tension between the early and late Universe. For JWST and WFIRST they are easier to detect than Cepheids and reach further than the TRGB. We propose to (1) study the long-period Miras in the type Ia supernova host galaxy NGC 2525 and (2) refine the Mira-based Hubble constant with 4 Mira-SN calibrators. To do this we request four epochs of NIR imaging toward this face-on spiral galaxy. We will combine these observations with archival data to form a continuous time series with a 1300 d baseline comma  from which we will derive the period and mean intensity of long-period Miras in this system. We will calibrate the PLR for long-period Miras and develop them as a new longer-range distance indicator. For the second task we will measure the NIR colors in NGC 2525 comma  NGC 1559 comma  NGC 5643 comma  and NGC 5861 in order to classify oxygen-rich Miras in these type Ia supernova hosts. The expanded Mira-SN calibrators and removal of carbon-rich Mira contamination will reduce the error in the current Mira-based Hubble constant by a factor of two.

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: With the detection of gravitational waves from merging compact objects comma  a new observational window onto the fates of massive stars has been opened. To explain the observed mergers of compact objects comma  we need accurate knowledge about the evolution of massive binary stars. Yet comma  current population synthesis calculations often yield puzzling results comma  as they predict certain types of stellar systems in large numbers comma  which are rarely observed. Whether this is due to observational challenges or due to errors in the underlying evolutionary models comma  is one of the major open questions in massive star research. In this proposal comma  we tackle two crucial stages of massive binary evolution that are predicted in large numbers comma  but so far rarely observeddoublePoint Systems containing an OB-star accompanied by an X-ray-quiet black hole (BH) and systems where a hot comma  envelope-stripped star is outshined by its OB-type companion. In both cases comma  the (compact) companion hardly leaves any trace in the optical beyond a suspicious comma  small He II disk-like emission. To identify the nature of the companion and distinguish between a BH and a stripped-star companion comma  UV spectroscopy is the only viable tool. With the unique capabilities of the HST comma  we will perform a pilot study for two prototypical systems in the Galaxy and the LMC that harbor either a BH or a stripped star companion. By determining the presence of tracing ions and the wind parameters of the stars comma  our study will confirm or deny the existence of the presently only known dormant BH in the Milky Way comma  marking an anchor point for our understanding of massive binary evolution and defining a framework for future observations of stripped stars.

description: This program is designed to verify acquisition parameters at LP6 and to produce spectra at several regions on the detector that would normally be used for target acquisition comma  but for which data are not downlinked as part of the acquisition process. The idea is that if anything does go wrong with the acquisition tests we will have maps of the detector that we can then use for diagnostics. LP6 is at +6.5d_comma from the on-axis detector position comma  The program uses ficticious offset targets to nod the telescope away from a centered target and then test the re-acquisition. Because these displacements need to happen along the AD and XD detector direction and target offset coordinates must be entered in RA and DEC comma  the ORIENT angle for each visit must be restricted to +-- 0.5 degrees comma  which also means a date range restriction. The date ranges and ORIENT restrictions for each visit are described in the program description. The program is modeled after the LP5 version of this programdoublePoint 16432. It uses the target WDG-1 (SK 191) and cenwave G160M-1577 for all exposures.  Prior to the execution of this program all LP6 SIAF comma  aperture mechnism positions comma  TA subarray comma  and foci must have been installed.  There is no special commanding in this program.

description: Ultra Diffuse Galaxies (UDGs) are galaxies with large effective radii but very low surface brightness. They were recently discovered in unprecedented numbers in the Coma Cluster comma  and are now being found in galaxy groups comma  and in isolation in the field. Their origin remains far from clear. In this proposal comma  we request time to observe a QSO that lies behind a gas rich UDG comma  using the COS G130M grating comma  in order to search for absorption lines from the interstellar and circumgalactic medium of the galaxy. The sightline to the QSO LBQS 1431+0142 passes within 11 kpc of the UDG ACG 242019 comma  a galaxy with an HI mass of 6x10elev8 solar masses comma  recovered recently in the ALFALFA survey from its 21 cm emission. This HI mass favors the detection of HI with a high column density in absorption towards the background QSO comma  which comma  in combination with metal lines comma  can be used to measure the metallicity of the CGM gas in the UDG. Such data can help constrain the origin of the galaxy. Comparison of our results with those from the population of Damped Lyman-alpha systems at higher redshift will begin to examine whether UDGs might contribute significantly to the population of QSO Absorption Line Systems in the universe.

description: The discrepancy between local measurements of the Hubble constant (H0) and the value inferred from observations of the CMB may be our strongest indication of physics beyond a Lambda-CDM cosmological model. Direct comma  distance-ladder measurements of the H0 rely primarily on Cepheids and the Tip of the Red Giant Branch (TRGB) to calibrate the luminosity of Type Ia supernovae (SN Ia). Here we propose an independent approach using Mira variables. Miras can check existing Cepheid and TRGB measurements while extending the distance ladder in the era of infrared space missions such as JWST and Roman Space Telescope comma  which will have difficulty discovering Cepheids. Miras are pulsating variable stars that follow tight (virgul0.12 mag scatter) Period-Luminosity Relations (PLRs) in the near-infrared (NIR). Short-period Miras (P < 400 d) have NIR luminosities up to 2 mag brighter than TRGB and are a ubiquitous older population that have already been used to calibrate H0 with 5% uncertainty. Long-period Miras (P > 400 d) are highly luminous and follow a different PLR from short-period Miras. We will (1) obtain a new distance measurement to this galaxy using short-period Miras comma  resulting in a sub-3% calibration of H0 with Miras when combined with existing Mira-SN Ia hosts  (2) discover long- period Miras with HST for the first time  (3) cross-correlate long-period variables discovered in HST with Spitzer IR observations. To do this comma  we propose to obtain 5 epochs of near-infrared observation in M101 comma  to study Miras in the field of SN Ia 2011fe. Combining these with archival observations of the late-time lightcurve of SN 2011fe results in virgul10 epochs of observation with a baseline of virgul3000 days.

description: This proposal will determine the exact spacecraft pointing offset and the aperture offsets needed for the 6th COS FUV lifetime position (LP6). The data from this program will be used to make minor adjustments to the Science Instrument Aperture File (SIAF) in order to center the target in the LP6 aperture comma  as well as allow for a check of the target acquisition centering algorithms.
