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: From Swift monitoring of the X-ray hardness variability of a sample of Seyfert-1 active galactic nuclei (AGN) comma  we have found a transient X-ray obscuration event in Mrk 841. This event was found on 2021-12-26 and confirmed again on 2022-01-02. We propose one non-disruptive HST-COS observation (1 orbit) to investigate the crucial association between the X-ray obscuration and the outflowing winds in AGN by high-resolution UV spectroscopy. Such obscuring outflows are remarkably different from the commonly-seen ionized outflows in AGN and can have important implications for the surrounding gas and the launching of AGN outflows. X-ray obscuration events have been captured with HST in only a few AGN so far comma  yet the scientific yield has been immense. However comma  there are still outstanding questions comma  which require further investigation of these events in additional AGN. This rare opportunity would help us in addressing the existing questions on obscuring outflows and broaden our understanding of the transient obscuration events in AGN.

description: This program determines the dispersion solutions for the FUV G160M grating at LP6. It observes the K2V emission-line star epsilon Eridani with all six G160M cenwaves. The G160M dispersion solutions are linear comma  so we will derive updated dispersion coefficients and zero points. Visit 01 observes with cenwaves 1533 comma  1577 comma  and 1589. Visit 02 observes with cenwaves 1600 comma  1611 comma  and 1623. Both visits start with a double ACQ-IMAGE for improved target centering comma  using the BOA and MirrorB.  The exposure times and the number of orbits requested are driven by the number of counts needed to achieve good cross-correlations using multiple chromospheric emission lines. We need to achieve at least S-N virgul 5 in the peaks of weaker emission lines. This is achieved with one orbit per cenwave. The dispersion coefficients of intermediate cenwaves can be constrained by those of shorter and longer ones comma  so these can accommodate the reduced exposure time that comes from sharing an orbit with the acquisition sequence.

description: A number of high-precision proper motion programs utilizing HST have already been used to study different aspects of the Magellanic Cloud system comma  thereby having a tremendous impact on our understanding of this pair of interacting galaxies and its relation to the Milky Way. It has been shown that both Clouds move much faster than previously assumed comma  suggesting they are most likely on a first passage around the Milky Way. Also comma  the internal rotation pattern of the Large Magellanic Cloud (LMC) in the plane of the sky has been revealed for the first time using data from HST. However comma  to date little is known about the dynamics of the star-cluster system within the LMC. To eliminate this lack of knowledge comma  we propose here for an additional epoch of HST observations for a sample of 19 massive LMC star clusters that span a wide range of ages and galactocentric distances to get comma  for the first time comma  a precise measurement of the clusters. proper motions. This program aims to use star clusters as tracers to probe the gravitational potential of the LMC comma  to study the kinematic pattern of the LMC as traced by star clusters at various ages and also to place important constraints on the interaction history of the Magellanic Cloud system.

description: Ganymede is the primary target of the upcoming JUICE mission comma  but many open questions currently exist about the unique magnetosphere-within-a-magnetosphere interaction between Ganymede and Jupiter.  The virgul10 degree offset between Jupiter.s rotation and magnetic axes leads to a time-varying interaction between the magnetospheres of the two bodies comma  with Ganymede encountering the densest Jovian plasma at System III longitudes around 110 and 290 degrees. Previous observations of Ganymede.s ultraviolet auroral emissions indicated that the orbital trailing and leading hemispheres respond differently to the changing plasma environment  the leading hemisphere emissions were found to be significantly more variable than the trailing emissions on a range of timescales. However comma  the two hemispheres were observed in different regions of System III longitude comma  and it is unclear if the difference in variability was real comma  or related to changes in the rate of reconnection with System III comma  as suggested by a recent analysis of radio observations. Our proposed program addresses this question by observing both hemispheres over a wide range of System III longitudes comma  including both plasma sheet crossings and regions of high and low radio emission probability comma  thereby conclusively determining whether the apparent disparate behavior of the two hemispheres is real. Our proposed observations comma  using COS G130M comma  will also provide the ability to test previous analysis of the expected O-O2 ratio in Ganymede.s atmosphere comma  and will place constraints on S ions local to Ganymede. An improved understanding of the near-Ganymede environment will provide useful information in advance of the JUICE mission.

description: This is a continuation of programs 11433 (SMOV) comma  11915 (Cy 17) comma  12338 (Cy 18) comma  12712 (Cy 19) comma  13098 (Cy 20) comma  13587 (Cy 21) comma  14029 (Cy 22) comma  14391 (Cy23) comma  14548 (Cy24) comma  14998 (Cy25) comma  15591 (Cy26) comma  15731 (Cy27) comma  and 16411 (Cy28). We study the stability and structure of the IR channel flat field images through all filter elements.  Flats are monitored comma  to capture any temporal trends and delta flats are produced.  High signal observations will provide a map of the pixel-to-pixel flat field structure comma  as well as identify the positions of any dust particles.  This version contains a full set of IR filter exposures once in the middle of the cycle. In addition we will acquire 3 exposures in each of the broadband filters F105W comma  F110W comma  F125W comma  F140W comma  and F160W twice during the cycle.  This work builds on the ISR of Ryan  and  Baggett (2015-011) and Ryan (2019-06).    ------ Calibration Justification -------  The target electrons per pixel is 40 comma 000 - 60 comma 000 comma  so that the Poisson noise of an individual pixel and a single exposure will be 0.5% comma  comparable to or smaller than any individual astronomical image made by WFC3 IR.  With 2 well-exposed flats per medium- and narrow-band filter comma  the Poisson-limited noise after combining 2 individuals will be virgul1.4x smaller.  For the broad-band filters comma  we can combine 3 exposures to produce bi-monthly flats comma  or combine a total of 18 exposures for a extremely low noise flats in the case temporal variations are limited.  Analysis results will be detailed in an ISR.

description: Omega Centauri appears to be the stripped nucleus of one of the largest satellite galaxies that has fallen into the Milky Way.  Yet the formation history of Omega Centauri is poorly understood due to the complexity of its stellar populations.  We propose to obtain WFC3-UVIS imaging to measure proper motions and use UV photometry to constrain stellar abundances and ages for hundreds of thousands of stars within Omega Centauri.s effective radius.   In combination with a MUSE spectral mosaic that will provide star-by-star metallicity and radial velocity measurements comma  we will create and publicly release an unprecedented catalog of 3-D stellar velocities comma  age estimates comma  and abundance information.  This combination of kinematic and stellar population information will enable us to study the details of both how and when Omega Centauri formed.  These results will provide insight on the galaxy in which Omega Centauri formed and its interaction with the Milky Way comma  and will serve as a template for understanding the formation and tidal stripping of nuclear star clusters.

description: This is a continuation and modification of Program 15761 and is to be executed this cycle for internal CTE. There are two epochs of observations comma  one set in November-December 2020 and the other in May-June 2021.  The charge transfer efficiency (CTE) of the ACS CCD detectors declines as damage due to on-orbit radiation exposure accumulates. This degradation will be monitored twice a cycle to determine the useful lifetime of the CCDs (prior to 2015 comma  cycles were only monitored once a year). All the data for this program is acquired using internal targets (LED) only comma  so all of the exposures should be taken during Earth occultation time (but not during SAA passages). This program emulates the majority of the ACS pre-flight ground calibration and post-launch SMOV testing (program 8948) comma  so that results from each epoch can be directly compared.  Extended pixel edge response (EPER) data will be collected over a range of six signal levelsdoublePoint 182 comma  430 comma  1620 comma  3400 comma  7100 comma  and 42 comma 000 electrons. The data will be 0.5-sec darks post-flashed to the given levels. The post-flash LED will be used at low and high current comma  and readout will use gain (CCDGAIN=2). Both parallel and serial CTE measurements can be made with the data. Both CCDAMP=AD and CCDAMP=BC will be monitored to test for CTE amplifier dependence. Shutter problems encountered during the first epoch of Program 15761 led to additional S-C exposures and containers being required to properly manage shutter behavior for EPER observations.

description: Despite using Type Ia supernovae (SN Ia) to precisely measure cosmological parameters comma  we still do not know basic facts about the progenitor systems and explosions. Theory suggests that SN Ia progenitor metallicity is correlated with peak luminosity comma  but not how quickly it fades comma  which we use to calibrate the luminosity and measure distances. This effect should lead to an increased Hubble scatter comma  reducing the precision with which we measure distances. If the mean progenitor metallicity changes with redshift or population comma  cosmological measurements such as the dark energy equation-of-state parameter and the Hubble constant could be biased. Models also indicate that changing progenitor metallicity will have little effect on the appearance of optical-NIR SN data comma  but significantly alter UV spectra. These data can only be obtained with HST.  Previous HST observations of 2 d_commatwind_comma SN (having nearly identical optical spectra and light-curve shapes) with different UV spectra and peak optical luminosities indicate progenitor metallicity differences consistent with models.  To determine the overall impact of progenitor metallicity on cosmological measurements comma  we must increase the sample.  The community now discovers virgul20 SN Ia each year >2 weeks before peak.  With the increased discovery rate of young SN comma  we can increase the sample of SN Ia with UV spectra near peak by 50% in a single Cycle. UV observations are critical to the understanding of SN Ia explosions and progenitors and constraining fundamental parameters such as the Hubble constant. This is our best opportunity to further our understanding of SN Ia while directly improving the utility of SN Ia for cosmology.

description: Monitor the spectroscopic sensitivity of the CCD using both low- and medium-resolution grating settings to reveal any contamination issues which might affect the spectroscopic throughput.  This calibration program will monitor the spectroscopic sensitivity of CCD spectroscopic settings using the same high-declination calibration standard.  Results will be ratioed to the first observations to detect any trends.  Every four months comma  the L-modes will be observed at settings which cover both the nominal position and the recommended E1 position which places the spectrum closer to the CCD readout.  These visits comprise one orbit for each visit.  This program also monitors the medium-resolution gratings comma  with one visit.  This visit takes observations at two central wavelength settings of G230MB and G430M comma  at each of the nominal and E1 pseduo-aperture positions comma  and at 1 central wavelength setting of G750M (with the addition of an observation at the pseudo-aperature position to that at the nominal position).  CTE will also be verified.
