description: The recently discovered GRB 210905A is the highest redshift GRB for which an early comma  high-S-N comma  mid-high resolution afterglow spectrum has been obtained. In addition to providing the redshift comma  this spectrum exhibits numerous metal lines and a complex velocity structure spanning virgul360 km-s comma  and blueshifted by virgul1000 km-s from a tentative Ly-a emission line. Modelling of the Lyman-alpha damping wing reveals the host column density comma  and puts constraints on the neutral fraction of the surrounding intergalactic medium. Analysis of the abundances gives an average metallicity ZvirgulZsol-20. In addition comma  the afterglow of this GRB started bright and has declined slowly comma  implying a late jet break. This suggests a wide jet and hence a particularly high energy event comma  perhaps indicative of an unusual progenitor star. Here we seek HST WFC3-IR F140W imaging to obtain a final late-time point on the afterglow light curve to constrain any break comma  and an image after the afterglow has faded comma  to provide a subtraction template and characterisation of the host galaxy. This would make it the first galaxy at z>6 detected in emission for which detailed absorption line abundances for multiple species are available.

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: Powerful radio galaxies have been unique probes of the distant Universe for many decades.  This proposal requests WFC3 G141 grism with F140W pre-imaging observations to confirm an emission line observed at 1.15 microns. A high continuum flux longward of this line (seen with the G141 grism and broad-band photometry) would confirm that this line is Lyman-alpha and hence this radio galaxy at z=8.45.  This detection would be the most distant super-massive black hole (SMBH) and active galactic nucleus (AGN) known.   At this redshift the radio galaxy would lie at the centre of a highly ionised Stromgren sphere with contributions to the ionising flux from the accretion onto the SMBH comma  inverse Compton emission from the jets comma  and star-formation.  As well as reaffirming the redshift of the host and challenging models of black hole formation comma  these observations will potentially reveal the complex interaction of this radio-loud AGN with its local environment.  Furthermore comma  confirmation of the existence of a luminous radio galaxy within the Epoch of Reionisation would allow studies of neutral hydrogen from absorption of the 21 cm line.  Due to the transmission of the Earth.s atmosphere at 1.15 microns comma  this observation would take >40 times longer if conducted from the ground (eight times longer if the spectrum is binned to the resolution of the G141 grism).

description: The joint gravitational wave and electromagnetic detections of the binary neutron star (BNS) merger GW170817 ushered in a new era of astrophysics. In the UV-optical-NIR the emission (a d_commakilonovad_comma) was powered by radioactive decay of nuclei produced via r-process nucleosynthesis. In the gamma-ray comma  X-ray comma  and radio the emission was instead powered by an off-axis jet typical of short gamma-ray bursts (SGRBs)  this connection was previously supported by the HST detection of a kilonova in the short GRB130603B. With only a single joint GW-EM detection and a single kilonova detection in an SGRB comma  the key frontier is to begin to map the distribution of merger outcomesdoublePoint ejecta mass comma  velocity comma  geometry comma  and nucleosynthetic yields. Here we propose to achieve this goal with HST observations of a kilonova associated with an SGRBs  observations of kilonovae in SGRBs are essential because the orientation is well known (face-on comma  along the binary.s angular momentum axis) and the LIGO-Virgo Observing Run 3 has not yielded joint GW-EM detections. Such a study can only be achieved with the sensitivity and resolution of HST comma  and it matches one of the d_commaspecial initiativesd_comma comma  namely deep NIR monitoring that is essential for informing future JWST follow-ups (d_commaJWST Preparatory Observationsd_comma). We request 10 orbits for 1 SGRB event. The HST observations will be supported by approved programs at Chandra comma  VLA comma  ALMA comma  Gemini comma  Keck comma  Magellan comma  MMT that will provide the targets comma  cover optical and early NIR follow-up to establish the baseline behavior comma  and complete the multi-wavelength picture of the event. Given the broad interest in this topic we waive the proprietary period.

description: Since 2014 comma  the symbiotic recurrent nova T Coronae Borealis has been in a high accretion rate state comma  rapidly accumulating the hydrogen-rich fuel that the massive white dwarf in this system will need for its next nova eruption comma  expected within several years. T CrB is evolving within this high state comma  with the optical light showing a gradual fading. XMM observations in 2017 comma  2018 comma  and 2020 comma  however comma  suggested that the accretion rate remained relatively constant. The observed differences appear to be caused by changes in the intrinsic absorber comma  probably related to the accretion disk wind. We therefore propose a set of two joint XMM -HST observations to monitor the accretion rate through the Keplerian disk and the boundary layer comma  and the amount of X-ray-UV absorber during this crucial period.

If uncorrected variations >1% are detected comma  the lamp spectra taken for generating PFLTFILE files will be used to create a new LFLTFILE following the discussion in ISR 1996-15. These data will also be used to test the improvements made by these new flat files.

description: In August 2020 we obtained spectroscopic confirmation of a gravitationally lensed arc at z=3.29 which is exceptionally bright.  At its redshift comma  or higher comma  it is the brightest arc known. The galaxy cluster responsible for the lensing is also extraordinarydoublePoint The cluster redshift is z=1.5 and the arc is seen at a large angular radius of 18d_comma comma  more extreme than any previously known cluster lens at these redshifts. The bright lensed source with a spectroscopically measured redshift provides a unique opportunity to use strong lensing to accurately constrain a cluster mass distribution at an early epoch where such measurements have previously not been possible. Through a modest investment of 3 HST orbits comma  this programme will both produce significant results on its own and be timely preparation for future observations of an extraordinary lensed source and lensing cluster in the coming JWST era.

description: Over the last 3 decades comma  X-ray(<60A) and UV(>700A) observations by Chandra and the Hubble Space Telescope (HST) have continuously revolutionised our understanding of Jupiter comma  but the planet has never been spatially resolved at wavelengths between the X-ray and UV. We propose to leverage and develop recent pioneering observing techniques with ChandraCORCHETE_OPENDrake et al. 2019CORCHETE_CLOSE to conduct the first spatially resolved EUV(60-170A) observations of Jupiter. This will open an entirely new window of exploration for Jupiter comma  revealing key information on the processes dominating rapidly-rotating bodies and gas giant planets. To do this comma  we request a 36ks observation of Jupiter with the Chandra HRC-S thin filter comma  a 6ks observation with the thick filter comma  and a simultaneous HST orbit to constrain the UV flux.

description: How much water did Mars lose over timequestionMark Can it be estimated by looking at the present value of the D-H ratio at MarsquestionMark The current picture of martian water escape estimates that Mars has lost virgul140 m of global equivalent layer (GEL) of water over its evolution history based on the enhanced D-H ratio of virgul4-8 times the value at Earth. Recently completed analysis of D and H Lyman alpha observations obtained by the Mars Atmosphere Volatile Evolution (MAVEN) mission show that the D and H exospheric densities undergo large changes in a short timescale of weeks. The present escape process that would facilitate such fast depletion of the column of D and H is insufficient to account for the magnitude of change observed comma  raising the likelihood of the presence of an energetic population of D and H created by non-thermal processes. The existence of such a population of H has been recently discovered with HST. The proposed 3-orbit observations with STIS is to discover energetic D atoms in the exosphere of Mars. The discovery and characterization of such a population is key towards determining the total water lost by Mars comma  and would increase the current estimates by a notable amount. The results from this observation program will also have significant effects towards our understanding of using the D-H metric in determining the total amount of water lost not only from Mars comma  but from other planetary atmospheres as well. This proposal supports the HST UV initiative.

description: The circumgalactic medium (CGM) mediates a galaxy.s accretion and feedback and may hold most of the metals it has ever produced. These findings derive from aggregating over ensembles of halos observed one galaxy at a time comma  and so they are limited in their ability to capture the rich density comma  temperature comma  and kinematic structure that simulations predict. Because its halo spans 30 degrees on the sky comma  Andromeda (M31) provides a unique opportunity to map the CGM of a single L* galaxy with dozens of sightlines and to relate the gas mass comma  metallicity comma  and kinematics to its detailed stellar populations resolved by complementary surveys. We propose to map the inner M31 CGM within 0.25 Rvir using 11 new QSOs and 2 M31 O stars comma  a region too sparsely sampled to characterize the most complex and influential region for galaxy evolution. When combined with existing M31 samples at larger radii comma  this unique program will enable compelling science goalsdoublePoint 1) to map ongoing accretion and feedback at the disk-halo interface comma  2) to fully characterize the CGM from the disk to 2 Rvir comma  3) to complete the CGM metals census that constrains outflows from the disk comma  and 4) to test feedback predictions from the latest zoom-in simulations of galaxy formation. Our program will also trace M31.s assembly history with deep parallel images of its stellar halo. This program will yield valuable new maps of the disk-halo connection comma  where CGM becomes ISM comma  in the only galaxy for which the effects of gas flows - such as chemical enrichment by specific feedback events - can be measured at this level of detail. Our study of M31 will be the most complete picture of a galaxy.s baryon cycle for the foreseeable future.
