title: A continuum of icy satellites’ radar properties explained by the coherent backscatter effect

description: The radar properties of icy satellites of Jupiter and Saturn commonly differ by more than an order of magnitude from those of rocky planets, due to the lower absorptivity of water ice than that of rock. However, the specific mechanisms behind these differences are not confidently known yet. Here we show that the global radar albedos and the circular polarisation ratios of icy satellites are correlated and vary together along a continuum, which is not satisfactorily explained by existing models. We modify a backscatter model that includes the coherent backscatter opposition effect (CBOE) and find that it fits successfully the observed continuum, indicative of CBOE’s primary role in driving the circular polarisation ratios of icy satellites. We predict that also the linear polarisation ratios and the incidence angle variation properties vary along the observed continuum, and that Europa and Enceladus have very heterogeneous surfaces/subsurfaces with very little microwave absorption. The modified CBOE model suggests that some worlds beyond Saturn’s orbit that are rich in non-water ices may have even more extreme radar properties.

title: BAT AGN Spectroscopic Survey – XIII. The nature of the most luminous obscured AGN in the low-redshift universe

description: We present a multi wavelength analysis of the 28 most luminous low-redshift narrow-line,ultra-hard X-ray selected active galactic nuclei (AGN) within the 70 month Swift/BAT all-skysurvey, with bolometric luminosities of log¹Lbolerg s􀀀1º &gt; 45:25. The broad goal of our studyis to determine whether these objects have any common characteristics, potentially settingthem aside from lower-luminosity obscured AGN in the local Universe. Our analysis relies onthe first data release of the BAT AGN Spectroscopic Survey (BASS/DR1) and on dedicatedobservations with the VLT, Palomar, and Keck observatories.We find that the vast majority ofour sources agree with commonly used AGN selection criteria which are based on emissionline ratios and on mid-infrared colours, and furthermore that our AGN are predominantlyhosted in massive, elliptical galaxies (9:8 &lt; log¹MMº &lt; 11:7). Otherwise, they do nothave common characteristics. Their radio luminosities, determined from publicly availablesurvey data, show a large spread of almost 4 orders of magnitude in - much broader than whatis found for lower X-ray luminosity, obscured AGN in BASS. Moreover, our sample showsno preferred combination of black hole masses (MBH) and/or Eddington ratio (Edd), covering7:5 &lt; log¹MBHMº &lt; 10:3 and 0:01 . Edd . 1. Based on the distribution of our sourcesin the Edd 􀀀 NH plane, we conclude that our sample is consistent with a scenario wherethe amount of obscuring material along the line of sight is determined by radiation pressureexerted by the AGN on the dusty circumnuclear gas.

title: Microbiome and Metagenome Analyses of a Closed Habitat During Human Occupation

description: Microbial contamination during long-term confinements of space exploration present potential risks for both crew members and spacecraft life support systems. As NASA prepares for manned missions beyond low Earth orbit, deeper into the solar system, the monitoring of microbial populations within closed human habitation will be necessary to ensure the safety of both the crew and the spacecraft. NASA’s Johnson Space Center recently developed a microbial swab kit, designed specifically to be used during astronaut Extravehicular Activity (EVA). The EVA swab kit was designed in such a way that it could be held easily within an astronaut’s bulky glove and or by a robot’s manipulator, making it suitable for microbial sample collection in remote and extreme environments. The previously tested (in laboratory and controlled settings) EVA swab kit was used in this study to sample various surfaces from a submerged, closed, analog habitat in order to characterize the microbial populations in this unique human habitat. Samples were collected from various locations across the habitat of which were constructed from various surface materials (linoleum, dry wall, particle board, glass, and metal) and microbial populations examined by culture, qPCR, microbiome 16S rRNA gene sequencing and shot gun metagenomics. Propidium monoazide treated samples identified the viable/intact microbial population of the habitat. The cultivable microbial population ranged from below the detection limit (BDL) to 106 CFU/sample and their identity was characterized using Sanger sequencing. Next-generation sequencing (NGS; both 16S rRNA amplicon and shotgun) were used to characterize the microbial dynamics, community profiles and functional attributes (metabolism, virulence, and antimicrobial resistance). The 16S rRNA amplicon sequencing revealed abundance of viable Actinobacteria (Brevibacterium, Nesternkonia, Mycobacterium, Pseudonocardia and Corynebacterium), Firmicutes (Virgibacillus, Staphylococcus and Oceanobacillus) and Proteobacteria (esp. Acinetobacter) on linoleum, dry wall, and particle board (LDP) surfaces, while members of Firmicutes (Leuconostocaceae) and Proteobacteria (Enterobacteriaceae) were high on the glass/metal surfaces. Non-metric multidimensional scaling (NMDS) determined from both 16S rRNA and metagenomic analyses revealed differential microbial speciation between LDP surfaces and glass/metal surfaces. The shotgun metagenomics sequencing showed bacterial predominance of Brevibacterium (53.6%), Brachybacterium (7.8%), Pseudonocardia (9.9%), Mycobacterium (3.7%), and Staphylococcus (2.1%); while fungal analyses revealed Aspergillus and Penicillium dominance.

title: End-of-mission calibration of the Cassini Imaging Science Subsystem

description: We provide an end-of-mission update to the in-flight calibration of the Imaging Science Subsystem cameras on the Cassini spacecraft, resolving discrepancies in our previous analyses from 2004 and 2010, incorporating data through the end of the mission, adding a correction for the weak but measurable camera sensitivity decline over time, and providing new transmission values for polarizing filters. In the new analysis, we add full-disk photometry of Jupiter and the Saturnian icy satellites Rhea, Dione and Enceladus to the previous measurements, which had consisted primarily of standard star targets, while the stellar photometry is updated to include a correction for light lost to the extended wings of the instrumental point spread function. The resulting absolute flux corrections differ considerably from those previously reported, shifting the measured flux by close to 10% in most broadband filters, and bringing agreement between star and satellite targets to within 3%. We also detail improvements to the narrow-angle camera flat field correction, and provide updates to the filter-by-filter point spread functions, hot pixel correction, and polarizer calibration. For the latter, we present new measurements of Titan’s polarization from near-UV to near-IR, including three methane bands and nearby spectral windows.

title: Near-surface atmospheric water vapor enhancement at the Mars Phoenix lander site

description: We used Phoenix Surface Stereo Imager data, constrained by other Phoenix and MRO data taken via a planned coordinated measurement campaign, along with radiative transfer modeling to assess the vertical water vapor profile at the Phoenix arctic location during its spring and summer mission. We examined 16 mid-afternoon observations spanning Ls=97.5º – 148º. We developed a 2-layer model of vapor distribution which reproduces the water vapor band depth. Using the results of the 2-layer model, we retrieved the mass mixing ratios in each layer and the implied surface vapor pressure. We found that near surface water vapor was enhanced relative to higher layers, resulting in a large percentage of the water column (&gt;25% and up to nearly 100%) confined below ~2.5 km.

title: Expanding the Y Dwarf Census with Spitzer Follow-up of the Coldest CatWISE Solar Neighborhood Discoveries

description: We present Spitzer 3.6m and 4.5m follow-up of 170 candidate extremely cool brown dwarfs newly discovered via the combination of WISE and NEOWISE imaging at 3􀀀5m. CatWISE, a joint analysis of archival WISE and NEOWISE data, has improved upon the motion measurements of AllWISE by leveraging a &gt;10 time baseline enhancement, from 0.5 years (AllWISE) to 6.5 years (CatWISE). As a result, CatWISE motion selection has yielded a large sample of previously unrecognized brown dwarf candidates, many of which have archival detections exclusively in the WISE 4.6m (W2) channel, suggesting that they could be both exceptionally cold and nearby. Where these objects go undetected in WISE W1 (3.4m), Spitzer can provide critically informative detections at 3.6m. Of our motion-conrmed discoveries, seventeen have a best-t Spitzer [3.6]􀀀[4.5] color most consistent with spectral type Y. CWISEP J144606.62􀀀231717.8 ( 1:300/yr) is likely the reddest, and therefore potentially coldest, member of our sample with a very uncertain [3.6]􀀀[4.5] color of 3.71 0.44 magnitudes. We also highlight our highest proper motion discovery, WISEA J153429.75􀀀104303.3, with 2:700/yr. Given that the prior list of conrmed and presumed Y dwarfs consists of just 27 objects, the Spitzer follow-up presented in this work has substantially expanded the sample of identied Y dwarfs. Our new discoveries thus represent signicant progress toward understanding the bottom of the substellar mass function, investigating the diversity of the Y dwarf population, and selecting optimal brown dwarf targets for JWST spectroscopy.

title: HISTOLOGICAL EVALUATION OF THE EFFECTS OF ACTION BITTERS ON THE TESTES OF ADULT MALE WISTAR RATS

description: Action Bitters, a popular herbal concoction, has been traditionally used to treat various health conditions, including those related to the male reproductive system. Despite its widespread use, there is a dearth of scientific evidence on its effects on the testes. This study aimed to investigate the histological changes in the testes of adult male Wistar rats following administration of Action Bitters.

Methods: Fifteen adult male Wistar rats were randomly divided into three groups (n = 5). Group A served as the normal control, while groups B and C received 10% (0.66ml/kg) and 5% (0.33ml/kg) lethal dose 50 (Ld50) of Action Bitters, respectively. The Ld50 values were calculated based on the median lethal dose of the herbal remedy. The rats were administered the herbal remedy for a period of one month, after which they were sacrificed, and their testes collected for histological examination.

Results: Microscopic examination of the testicular tissue samples revealed no evidence of abnormal cellular changes or tissue damage. The tissue samples appeared normal, with no signs of inflammation, necrosis, or apoptosis.

Discussion: The findings of this study suggest that Action Bitters does not induce histological changes in the testes of adult male Wistar rats. These results provide new insights into the potential mechanism of action of the herbal medication on testicular function. The study highlights the importance of considering both histological and biochemical assessments when evaluating the effects of herbal remedies on reproductive health.

Conclusion: This study contributes to the growing body of knowledge on the effects of herbal remedies on the male reproductive system. The findings suggest that Action Bitters may be a safe and effective herbal remedy for treating reproductive health issues, and further research is warranted to explore its potential benefits and mechanisms of action.
