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: We propose XMM-Newton+HST observations of SPT-CLJ2228-5828 comma  a high-redshift (z = 0.73) candidate for a dissociative galaxy cluster merger. It exhibits two major comma  widely-separated (940 kpc) centers in the galaxy distribution with (noisy) counterparts identified in an initial weak lensing analysis of the cluster. Traced by the SPT Sunyaev Zel.dovich signature comma  the hot intracluster plasma appears to be located in the middle between the two peaks of the galaxy distribution and mass map comma  suggesting a violent comma  dissociative merger. If confirmed comma  SPT-CLJ2228-5828 would be among the widest dissociated mergers known. These systems are extremely rare comma  especially at high redshifts comma  and provide the best conditions for constraints on the dark matter self-interaction cross-section. The requested high-resolution X-ray observations will enable us to to efficiently confirm the dissociated merger nature. Additionally comma  they will allow us to constrain the cluster X-ray temperature and luminosity to 10% comma  providing the precision needed to compare its properties to its peers among the rarest violent cluster mergers known. We also request complementary HST observations to substantially improve the mass reconstruction using strong and weak gravitational lensing. This will not only allow us to compute constraints on the dark matter self-interaction from the system comma  but also to compare the cluster properties to expectations from mass-observable scaling relations. Complementary GMOS multi-object spectroscopy for the cluster has already been approved comma  yielding the final piece needed for a comprehensive multi-wavelength analysis of this extreme cluster.

description: Supernova (SN) 2021gno in NGC 4165 (D=30.5 Mpc) is the second closest known Calcium-rich (Ca-rich) transient and only the second object in this class with an X-ray detection. Prompt comma  high-cadence follow-up of this transient across the EM spectrum has indicated that the progenitor star was likely low mass (e.g. comma  white dwarf or <10 Msun) and surrounded by dense circumstellar material (CSM) whose geometry-density was capable of producing luminous X-ray emission as well as a double-peaked light curve. The close proximity of SN 2021gno provides only the second opportunity to track the photometric evolution of a Ca-rich transient at late phases (>300 days) when the SN luminosity is governed by radioactive decay and-or additional power sources e.g. comma  CSM comma  and is too faint for ground-based observatories. These objects typically decrease in magnitude rapidly and thus their late-time decline rate and power source remains ambiguous. Here we propose multi-color imaging of SN 2021gno in order to understand its late-time bolometric behavior and to constrain the total masses of radioactive decay isotopes Ni-56 and Ni-57 synthesized in the explosion. This will allow us to test whether SN 2021gno is powered solely by radioactive decay or by additional CSM at large distances from the progenitor system.

description: SN 1987A is the great supernova (SN) of the HST era. An unbroken string of observations is the essential tool for detecting change and establishing a uniform legacy archive. Recent imaging has shown dramatic changes in the ejecta and the interaction with the circumstellar material. After a steady increase in flux comma  the inner circumstellar ring reached a maximum in 2009 and is now fading rapidly as it is destroyed by shocks. At the same time comma  diffuse emission and new spots outside the inner ring are becoming visible comma  gradually revealing previously unseen material that extends toward the outer rings. Monitoring this emission is required to understand the formation of the rings and the mass-loss history of the progenitor star. In addition comma  the expanding innermost ejecta reveal asymmetries and mixing in the explosion. As the ejecta expand comma  X-rays from the inner ring penetrate into the metal-rich core comma  which results in a brightening in the optical band. We request imaging in narrow and broad filters over the next three cycles to follow these developments. Annual observations are needed to monitor the rapid evolution of the shocks. Imaging in additional filters in one of the cycles will provide flux measurements crucial to estimating the energy budget of the ejecta comma  that comma  perhaps comma  will begin to reveal the elusive compact object. The HST observations have a unique blend of photometric fidelity and angular resolution that make them the indispensable partner to ongoing X-ray comma  sub-mm ALMA comma  and ground-based optical-NIR observations. They are also an important complement to the JWST GTO observations in 2022.

description: Ly-alpha (LyA) is the strongest feature in the rest-frame far-UV emission-line spectra of galaxies and our most reliable indicator of leaking ionizing photons. However comma  the intergalactic medium is increasingly neutral at higher redshifts comma  attenuating both ionizing and LyA emission from galaxies within the epoch of reionization (EoR). Additionally comma  LyA provides a limited tracer of the escaping ionizing radiation as it probes the low-ionization  gas properties (close to the H-ionizing edge at 912 A comma  13.6 eV) comma  while the ionizing continuum peaks at significantly higher energies (500 A or 24.6 eV). Higher-energy photons significantly contribute to reionizing the neutral hydrogen as they can each ionize 2 H atoms comma  nevertheless comma  their escape-fraction is dramatically underestimated by the standard measurement of the ionizing photon escape at 900 A.  To map the escape of ionizing photons across the full ionizing continuum for the first time comma  we propose to combine archival and new HST-COS G130M+G160M observations of the LyA and C IV emission profiles of 10 nearby extreme UV emission-line galaxies. LyA and C IV probe different ionization stages (low and high comma  respectively) of the gas comma  and thus different energies of ionizing photons. Therefore comma  these high-resolution observations will enable us to determine the column densities of the low and high ionization gas comma  estimate the fraction of both low- and high-energy photons escaping EoR systems comma  and provide reliable diagnostics from emission line features observable in the early universe comma  which is critical for interpreting FUV emission-line features in forthcoming spectra of high-z galaxies with JWST.

description: The purpose of this program is to monitor charge traps in the ACS-WFC CCDs at the lowest charge level and update the pixel-based CTE model parameters as needed. As shown in ACS ISR 2018-04 comma  the number of traps affecting small to medium-size charge packets can be inferred from the shape of warm pixel trails in short darks with a range of background (post-flash) levels. A new comma  more direct approach to pinning the CTE model has been developed to compare these data to scaled long (1000s) darks from the Daily Monitor program. By examining the survival of WPs as a function of row number and post-flash level comma  we can develop a direct model for CTE losses.

description: Dense protoclusters of bright submillimeter galaxies are the suspected progenitors of today.s massive clusters comma  but the mechanisms that govern their triggering and transition to compact quiescent galaxies by z virgul 2 are not well understood. These processes are hinted at by millimeter spectral line profiles comma  but are only fully resolved at sub-arcsecond scales comma  which cannot be imaged efficiently with ground-based telescopes in the Northern hemisphere. We propose to constrain the morphology of the stars in the two submillimeter-brightest galaxies in a newly identified comma  spectroscopically confirmed protocluster at z = 3.14. This requires 5 total orbits with WFC3-IR comma  with 3 orbits with F110W and 2 orbits with F160W. The protocluster lies in the GOODS-North and has extensive multi-wavelength coverage comma  but is just outside the coverage of HST-ACS and WFC3 from the original GOODS and CANDELS surveys comma  such that no sufficiently high-resolution imaging of this field currently exists. The two galaxies have spectroscopic redshifts from CO line scans with NOEMA comma  but their CO(5-4) line profiles are different comma  suggesting different stages or mechanisms of triggering. The 0.15.. resolution of the proposed observations will resolve close mergers and-or compact stellar counterparts. Our virgul9 square arminute coverage will also serendipitously detect the near-IR counterparts of many fainter submillimeter galaxies in this dense field. The identification of advanced mergers or compact stellar counterparts in these galaxies comma  which can trace ongoing triggering or quenching comma  respectively comma  will be used to prioritize targets for high-resolution millimeter interferometric follow-up.

description: The lowest mass galaxies known to date - aptly named .ultra-faint dwarf galaxies. - orbit the Milky Way (MW) as satellites. Follow-up study of these objects have revealed systems that are the oldest comma  most metal-poor comma  and most dark matter-dominated galaxies known. They hold the potential for constraining dark matter on small scales comma  placing limits on the mass threshold for successful galaxy formation comma  and defining the impact reionization has on small galaxy halos. Such galaxies are predicted to be present in large numbers in the Local Group (and throughout the universe) comma  yet they have belied detection due the challenges in finding instrinsically small and faint systems in a very big sky.   We have discovered three ultra-faint dwarf galaxy candidates in the Dark Energy Spectrscopic Instrument (DESI) Legacy imaging data located outside the halo of the MW at distances estimated to be between 0.4-0.7 Mpc. In contrast to the population of ultra-faint dwarfs discovered as satellites of the MW comma  these galaxy candidates appear to be outside the halo of the MW system comma  providing a unique opportunity to test galaxy formation theories without the competing effects of a halo environment. We request 1 orbit of HST per target to confirm their detection comma  measure secure distances comma  and determine their structural properties. Their properties will be compared with those of ultra-faint dwarf satellites of MW and M31 comma  as well as isolated very low-mass galaxies. We will determine their star formation histories from their resolved stellar populations to test whether they are quenched comma  have extended (or delayed) star formation over cosmic times comma  or distinct characteristics.

description: This is a continuation and modification of Program 16381 and is to be executed this cycle for internal CTE. There are two epochs of observations comma  one set in November-December 2021 and the other in May-June 2022.  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 2 (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: Perform routine monitoring of FUV XDL detector dark rate. The main purpose is to look for evidence of a change in the dark rate comma  both to track on orbit time dependence and to check for a detector problem developing. Variations of count rates as a function of orbital positions will be analyzed to study the effect of SAA. Stacked images will help us study the spatial distribution of dark rates on the detector.
