title: SH1284279.09FU

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 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: Despite the success of galaxy formation models comma  some questions remain largely unanswered. Chief among thesedoublePoint (1) how did galaxies reionize the universe (if they did)questionMark (2) How do they evolvequestionMark (3) How do gas and metals cycle in and out of galaxiesquestionMark JWST will undoubtedly help us advance galaxy formation and evolution science. However comma  to answer these and many other questions comma   deep rest-frame UV and optical data will still be required. Given JWST.s limited lifetime comma  it is essential to obtain ancillary data crucial for its success.  The JWST GTO program CANUCS (CAnadian NIRISS Unbiased Cluster Survey) aims to answer these questions by observing five galaxy clusters and ten parallel fields for 200 hours with NIRISS grisms comma  NIRCam imager comma  and NIRSpec multi-object spectrograph. However comma  only in conjunction with the proposed deep comma   high-resolution optical data will it determinedoublePoint (1) Lyman-alpha observability of a sample of >1000 galaxies at z > 6 well into the reionization epoch. (2) Robustly determine star formation histories of >10 comma 000 cosmic-noon galaxies. (3) Study metallicity gradients of >200 dwarf galaxies in a large and well-defined sample at cosmic noon. This proposal will deliver uniform and essential data using ACS F435W and F606W for the CANUCS clusters comma  perform a supernova search and explore extraordinary objects comma  including a galaxy similar to the host of supernova Refsdal and an intrinsically faint comma  low-mass confirmed z>7 source. This proposal will provide an extremely valuable data set for the whole community comma  and we waive any proprietary rights for this proposal.

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 10 yr post-explosion UV-optical imaging of the remarkable transient SN 2009ip comma  in order to determine its ultimate fate.  This object was discovered in a non-terminal eruption in 2009 comma  and then appeared to explode in a much more extreme supernova (SN)-like event in 2012.  A very massive (80 Msun) quiescent progenitor was identified in an archival HST image comma  and the star had several luminous blue variable (LBV)-like eruptions before 2012.  Many SNe IIn are inferred to have LBV progenitors to make their dense circumstellar material (CSM) comma  but SN2009ip is an extraordinary case where the LBV-like progenitor was detected directly comma  and where spectra of numerous pre-SN eruptions were obtained. No other SN has this treasure trove of detailed information about the progenitor (not even SN1987A).  This was one of the most important transient events of the past decade comma  because if it was a true core-collapse (CC) SN comma  then it is the first definitive case of a very massive star above 30 Msun that went SN and didn.t collapse to a black hole.  However comma  the interpretation of SN2009ip as a true CCSN is controversial for 2 reasonsdoublePoint (1) its lightcurve could also be explained by shell collisions from non-terminal explosive transients comma  and (2) the tell-tale signs of nucleosynthetic products comma  if present comma  were largely masked by CSM interaction.  As with all SN progenitor candidates comma  proof that the star is dead requires that it disappear in late time data.  Five years ago the source was only marginally fainter than the progenitor and apparently still fading.   Cycle 29 will be 10 years since explosion.  Our proposed observations will determine once and for all if the progenitor is gone.

description: The asymetric magnetosphere of Uranus is now approaching southern solstice comma  gradually shifting from its equinox-to-solstice intermediate geometry. We propose to image the UV (H and H2) aurorae of Uranus with STIS and ACS instruments near next opposition with a two-fold objective. We first aim at investigating the current comma  poorly known comma  magnetospheric configuration in which a diversity of UV aurorae comma  probing various acceleration mechanisms comma  is expected to co-exist. The observations will be carefully scheduled to sample variable solar wind conditions and all planetary longitudes to asses the solar wind-magnetosphere interaction. The aurorae will then be accurately fitted by model auroral ovals to retrieve the position of the magnetic poles. This reference will then be used comma  on the  one hand to further constrain the inner rotation rate and the associated SIII longitude system and comma  on the other hand to analyze planned coordinated observations of the planet by JWST in the NIR and by XMM-Newton at X-ray wavelengths.

description: The COS Target Acquisition (TA) monitor is divided into two pieces comma  NUV and FUV. This program is the FUV portion and is designed specifically for FUV LP4. FUV LP4 uses NUM_POS > 1 PEAKXDs for cross-dispersion TA. All previous LPs used NUM_POS=1 PEAKXDs. The NUM_POS=1 PEAKXDs required the routine monitoring of the grating-dependent WCA-to-PSA offsets. The NUM_POS >1 PEAKXDs do not use these flight software (FSW) patchable constants as they use the LTAPKD FSW macro used in ACQ-PEAKD comma  but re-purposed for use in the cross-dispersion (XD).  This program uses the HST standard star  WD1657+343. This target was used previously in the COS TA Monitor programs comma  13124 (C20) comma  13526 (C21) comma  13972 (C22) comma  14440 (C23) comma  14857 (C24) comma  15386 (C25) comma   15537 (C26) and 15775 (C27). We re-use this target here as it is safe with PSA-MIRRORA and visible almost year-round.

description: The NIR-MIR SED of galaxies is dominated by spectral features from polycyclic aromatic hydrocarbon (PAH) molecules fluorescing in regions illuminated by FUV photons. In low metallicity systems (Z < 0.2 Zo) comma  previous studies with Spitzer have revealed a substantial deficiency in the emission and abundance of PAHs comma  the origin of which remains unexplained due to the lack of deep comma  resolved comma  multi-band photometry or spectroscopy. We will obtain NIRCam and MIRI imaging to observe the 3.3 comma  7.7 comma  and 11.3 micron PAH features in dusty star-forming regions in two low metallicity galaxies comma  IC 1613 (15% solar) and Sextans A (8% solar). Additionally comma  we will obtain HST-WFC3 imaging with F275W comma  F336W comma  F475W comma  and F814W to complement the JWST observations. The HST observations will allow us to derive extinction maps comma  which will be used to normalize the PAH abundance to that of big grains. To obtain the extinction maps comma  we will fit the NUV-NIR SED of thousands of stars  in the HST and JWST images with the BEAST code (Gordon+2016) in order to constrain the stellar mass comma  age and dust extinction (A_V) toward each sight-line. A_V measurements toward individual stars will be combined on the sky to produce the extinction maps.  The observations will allow us to 1) estimate the PAH properties comma  particularly their abundance comma  ionized fraction comma  and size distribution  and 2) correlate those properties with other tracers of the ISM comma  such as the star formation rate density comma  the distance and UV spectrum of massive stars comma  the  distance to PAH-producing stellar sources comma  the ISM column density of gas and dust comma  and gas-phase abundances.  By observing how the PAH properties and abundance vary with environment comma  we will constrain the mechanisms responsible for the formation comma  destruction comma  excitation comma  and low abundance of  PAHs in those poorly shielded low metallicity environments. Since JWST will measure star formation rates as low as 10 Mo-yr from PAH emission at the peak of cosmic star formation at redshift zvirgul2 when the average metallicity of the universe was about 10% solar comma  it is crucial that we deepen our physical understanding of PAHs at low metallicity.

description: Recent understanding of HST-STIS coronagraphic high contrast imaging mode can enable the study of quasar surroundings in visible light at high-contrast and high-resolution. We request 8 orbits of coronagraphic imaging mode to observe the surrounding environments for quasar 3C 273 with STIS as a first extragalactic science demonstration of this mode. Using the recently commissioned BAR5 occulter comma  we can probe the host galaxy morphology and features of the quasar.s circumnuclear environment down to 0.2 arcsec comma  or virgul520 pc. In our preparatory work comma  on the one hand comma  we have discovered new host galaxy structures at virgul1 arcsec in the re-analysis of non-coronagraphic STIS observations of 3C 273  on the other hand comma  our pilot Keck-NIRC2 near-IR observation has revealed a candidate circumnuclear disk with a diameter of virgul1 kpc. Coronagraphic observations with STIS will not only help characterize this candidate structure comma  provide critical constraints for determining whether the host galaxy is undergoing a merger comma  but also provide an unprecedented view of the surroundings of 3C 273 in visible light. Moreover comma  combined with archival re-analysis comma  we can establish a virgul20 year baseline to study apparent motion for its jet. This project further demonstrates the necessity of multi-instrument coronagraphic imaging from visble to near-infrared in understanding the surrounding environments of quasars.
