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 NASA DART impact into one component of the Didymos-Dimorphos binary asteroid occurred on UT 2022 September 26. Images taken at the impact time show a spectacular comma  structured cloud of ejecta and comma  on later dates comma  the emergence of a long comma  radiation-pressure swept tail of particles.  Here comma  we propose a 4 orbit program to observe the DART-produced debris some 10 weeks after the impact comma  from a perspective within the projected orbit plane of the system.  This observing geometry comma  in conjunction with an existing dynamics model comma  will provide a unique measure of the quantity and of the size and velocity distributions of the larger ejecta particles comma  and we also expect to detect individual macroscopic fragments (boulders) in the ejecta trail.  The measurement is highly complementary to the 19 orbit HST program GO 16674 comma  whose final observation was taken on October 15.  The proposed observation will extend the time base of data from less than three weeks to ten comma  and provide the strongest ejection constraints and the ultimate record of this unique impact experiment.  Having an exactly known impact time and projectile energy comma  the DART impact also provides an important means to interpret existing and future observations of colliding asteroids comma  which are also known to produce structured ejecta fields and long trails of debris.

description: We request a Chandra observation (80 ks) of two very rare objects that fall within the same field of viewdoublePoint the strong intermediate-mass black hole candidate ESO 243-49 HLX-1 and a newborn hard tidal disruption event (TDE). For HLX-1 comma  which has been in a prolonged low state for nearly 4 yr comma  the data will be crucial to measure the current level of the low state and test two competing models for the formation of the system. Five HST orbits are also requested to pin down the host population and age by measuring the host in UV and optical when the contamination from the central source is minimal. For the new hard TDE comma  our goal is to constrain its long-term X-ray evolution comma  especially to detect the fast drop comma  which would be a strong indicator of a jet being shut off.

description: After a 10-year hiatus comma  Mrk 590 has rekindled its nuclear activity and is now strongly flaring in a low X-ray state. This offers a very rare opportunity to follow in real time the onset of AGN activity that can lead to better insights on the AGN central engine physics. While directly impacting galaxy evolution through energetic feedback comma  the AGN structure and physics are still poorly understood. We wish to catch the early onset of AGN activity to test details of AGN accretion physics that cannot be constrained in any other way.  We propose a ToO program to obtain four COS spectra of Mrk 590 at different X-ray flux levels as its AGN builds up. We will measure UV broad-line fluxes comma  constrain the UV and EUV ionizing continuum emission from the accretion disk comma  and establish the critical ionizing luminosity required for broad-line production comma  something that is still V1.0. This allows us to test theoretical model predictions for the broad-line region physics. The efficient strategy we employ ensures that instructive constraints are obtained with a very modest HST program - yet comma  the full time request may not be needed. HST is the only telescope that can obtain spectra of the far-UV emission below 1900A that are crucial to reach our science goals.   By combining this HST program with observations obtained with Swift comma  NuSTAR comma  XMM and VLT we will provide a comprehensive account of the black hole accretion state changes during the early onset of AGN activity as the AGN builds up. These HST-COS data will contribute with unique information to the legacy database on this intriguing object that will undoubtedly spawn new insight on AGN physics and the changing-look AGN phenomenon.

description: The recent discovery of the seven planet TRAPPIST--1 system comma  including three habitable zone planets comma  has opened up a new avenue for studying temperate terrrestrial planets comma  with potentially habitable atmospheres. This system and others like it around the lowest-mass stars will be prime targets for both planet searches and studies to directly characterize the atmospheres of Earth-sized exoplanets. Understanding these atmospheric observations and the potential prospect of such exoplanets to develop and sustain life critically depends on the high-energy stellar radiation environment from X-ray to ultraviolent wavelengths because of the ability of this emission to drive atmospheric mass-loss comma  and it.s strong influence on planetary photochemistry comma  including its ability to catalyze prebiotic chemical pathways. However comma  little is known about the X-ray to UV radiation field of stars at the end of the main sequence. We propose a survey of the joint X-ray and UV emission of a sample of M7-M9 dwarfs comma  to provide the basis for estimating the high-energy stellar radiation environment around these stars across a range of activity levels comma  and to use these spectral observations as inputs to planetary photochemsitry models. Furthermore comma  these observations will probe the nature of chromospheric and coronal heating in the coolest stellar atmospheres.

description: This program is designed to search for the best focus for the G130M-1222 and G160M-1600 settings at Lifetime Position 6 (LP6) at +6.5d_comma on the FUV detector. The focus sweeps are designed to determine the best focus position to within 100 steps comma  and will scan at 200 focus step increments from -1000 to +1000 relative to the predicted best focuses for the G130M-1222 and G160M-1600 settings which were determined by extrapolation from the adjacent exploratory sweep at +7d_comma. This strategy is based on several earlier programs (PIDs 13635 comma  14527 comma  15451 comma  16431 comma  16491) comma  which all executed successfully. We will adjust the focus in steps of 200 as is typical for focus sweeps comma  with finer comma  100 step increments between relative focus steps of CORCHETE_OPEN-200 comma +200CORCHETE_CLOSE  The target for this program is AzV 75 comma  as this star is visible with HST during the required operation window (Nov-Dec comma  2021). This program also includes a backup target comma  Feige 48 comma  with visits which would be observed in late Dec. 2021 - early Jan. 2022. The exposure times at each step are defined to provide spectra with S-N virgul 30 in the faintest portion of each spectrum.

description: The galaxy population observed near cosmic noon (at redshift z=1-2) shows numerous differences from that in the nearby universe.  Since we have only been able to study the integrated light of galaxies at z=1-2 comma  however comma  we do not know whether their luminous stellar populations comma  which drive galaxy evolution comma  may also be distinct. Separately comma  the constituents of dark matter remain unidentified comma  and current limits would allow a small population of primordial black holes (PBHs) formed during inflation.  The Hubble Space Telescope has recently been used to find individual comma  luminous stars at z=1-2 that are highly magnified by foreground galaxy clusters. As a background magnified star becomes aligned with a star or remnant in the foreground cluster comma  its magnification and apparent brightness can change. Using the same stellar population synthesis models that are applied to interpret galaxies at z=1-2 comma  we find that the observed microlensing events are both brighter and more numerous than expected. PBHs responsible for 1-2% of dark matter could explain the events comma  while revised stellar evolution models with additional blue supergiants (BSGs) comma  which match the photometry of two lensed stars comma  may present an alternative.  Here we propose a SNAP program to image cluster fields that contain blue comma  bright giant arcs having luminous stars close the galaxy cluster.s critical curve. The survey will be able to distinguish between PBHs accounting for 2% of dark matter comma  and an excess of luminous BSGs comma  some of which should always be detectable (<28 mag). We will be able to provide targets for James Webb Space Telescope spectroscopy and draw comparisons with nearby luminous stellar populations.

description: The discovery that exoplanetary systems are common has posed the overarching question of how closely they resemble the Solar System. Although we have learned of many cases with dramatic differences comma  this perspective may be more a product of selection effects than of the general population. Systems where we can achieve au (or even sub-au) resolution hold the keys to understanding exoplanetary system structure at the necessary scale. At 7.7 parsecs comma  Vega enables one of the highest spatial resolution imaging opportunities of all exoplanetary systems. For example comma  its Kuiper-belt analog ring located at virgul 120 au is at an angular separation of 16.9.. comma  while its Asteroid-belt analog is at virgul 12 au (corresponding to 1.6..). Giant and ice-giant planets will also likely be outward of 30 au (virgul 4..) from the central star. At these angular distances comma  the STIS coronagraph has excellent imaging contrast. Furthermore comma  the luminous host star provides ample flux at optical wavelengths for the dust and planetary bodies in the system to scatter. Despite these attributes comma  the Vega disk has never been imaged with HST comma  and attempts to image its planets in scattered light integrated only deep enough to detect planets with radii above 3.6 R_Jupiter (at which sizes gas giants are not expected to exist). We propose a single heritage HST program that will provide a deep and complete characterization of the Vega debris and planetary system. Our program is designed to image the disk components and any Jupiter analogs outward of 30 au comma  assuming conservative albedo values. Our HST observations will complement JWST GTO Cycle 1 observations of the system with NIRCam and MIRI and existing ALMA observations.

description: Lyman-alpha transit observations of warm comma  gas-rich exoplanets enable the study of active atmospheric loss. However comma  obscuration of the inner +--30 km-s of the Lyman-alpha core by the interstellar medium (ISM) severs a key link between the velocities at which planetary outflows are observed and the virgul10 km-s velocity at which they initially depart the planet. Systems with high radial velocities (RVs) can circumvent this limitation by Doppler-shifting the Lyman-alpha core away from ISM absorption. We propose Lyman-alpha line core transit observations of HD 136352 c comma  a transiting warm sub-Neptune orbiting a nearby solar analog. HD 136352 c is presently uniquely suited to these observations. However comma  because of the diagnostic power of transit observations in the Lyman-alpha line core comma  we also include a Lyman-alpha survey of 5 additional high RV targets hosting warm comma  gas-rich planets to confirm Lyman-alpha core visibility in an expected 1-3 systems. These Lyman-alpha transit observations of HD 136352 c and comma  in future cycles comma  the 1-3 systems found to have exposed line cores will provide an observational link between material accelerated beyond the 30 km-s limit and its source at the planet. This will provide new constraints on the interactions between planetary outflows and their circumstellar environments comma  ultimately improving model-dependent mass loss estimates and providing insight into the impact of hydrodynamic atmospheric loss on the evolution of planetary populations.
