SERGEI YESENIN’S TO PUSHKIN IN THE CONTEXT OF HIS WORK
Authors: Савченко Т.К. 
Published: April 2024

В статье анализируется стихотворение С. А. Есенина «Пушкину» с его жанровыми признаками одновременно послания и посвящения, занимающее одно из центральных мест в творчестве поэта. Мотивом памятника Есенин продолжает исконную традицию как русской, так и мировой литературы. Прослеживается история создания произведения, выразившего стремление автора порвать с «богемой» после определенного этапа его творчества – создания поэтического цикла «Москва кабацкая». Творческую эволюцию Есенина на данном этапе подмечала как советская, так и эмигрантская критика. Подчеркивается сходство лирических героев обоих поэтов и доказывается: культовое отношение к Пушкину является одной из важнейших черт есенинского мифотворчества. В этом контексте он отождествляет судьбы – свою и Пушкина, творчество которого для него – эталон поэтического мастерства. В словах Есенина – «Постичь Пушкина – это уже нужно иметь талант» – заключено убеждение: звание подлинного поэта прямо зависит от его способности разгадать тайну гения Пушкина.
The article looks into Sergei Yesenin’s poem «To Pushkin», whose genre can be defined both as an epistle and a dedication. It is one of the most essential pieces in the poet’s body of work. With its subject matter, a monument, Yesenin perpetuates a long-standing tradition of both Russian and world literatures. The article traces the history of the creation of the poem, which is emblematic of the author’s desire to break up with bohemianism after a certain period in his writing during which he penned the poem cycle «Moscow of the Taverns». Yesenin’s artistic evolution «towards Pushkin» has been noted by both Soviet and émigré critics. The article stresses the similarity of both poets’ lyrical subjects and demonstrates that the cult of Pushkin was one of the most important features of Yesenin’s myth-making. In this context he identified his own fate with Pushkin’s, whose work for him was the standard of poetic skill. When Yesenin wrote that «to understand Pushkin, one must already have some talent», he meant that to be a real poet, one had to be able to find out the secret of Pushkin’s genius.
PUSHKIN - AN IMAGE AND A PRECEDENT PHENOMENON IN RUSSIAN SONG TEXTS OF THE 20TH–21ST CENTURIES
Authors: Матрусова А.Н. , Соломонова А.А. 
Published: April 2024

В статье поднимается вопрос о функционировании имени Пушкина как прецедентного феномена в русской песенной поэзии от второй трети ХХ века до первой четверти XXI века. Отмечается, что прецедентность самого имени органично сочетается с использованием цитат пушкинских текстов, отсылками к биографии поэта и культурному контексту как Пушкинской, так и современной эпохи. В связи с этим авторы приходят к выводу, что потенциал прецедентности таких имен, как Пушкин, не снижается, а, скорее, наоборот, нарастает по мере изменения и раскрепощения текстовой песенной культуры современного русскоязычного пространства.
The article raises the question of the functioning of the name Pushkin as a precedent phenomenon in Russian song poetry from the second third of the 20th century to the first quarter of the 21st century. It is noted that the precedent nature of the name itself is organically combined with the use of quotations from Pushkin’s texts, references to the poet’s biography and the cultural context of both Pushkin and the modern era. In this regard, the authors come to the conclusion that the precedent potential of such names as Pushkin does not decrease, but rather, on the contrary, increases as the textual song culture of the modern Russian-speaking space changes and becomes emancipated.

On the Rigidly Precessing, Eccentric Gas Disk Orbiting the White Dwarf SDSS J1228+1040
Authors: Goksu Olcay Ates , Kutra Taylor , Wu Yanqin 
Published: April 2024

Abstract
Metal pollution onto white dwarfs is a widespread phenomenon that remains puzzling. Some of these white dwarfs also harbor gaseous debris disks. Emission lines from these disks open a unique window to the physical properties of the polluting material, lending insights into their origin. We model the emission line kinematics for the gas disk around SDSS J1228+1040, a system that has been monitored for over two decades. We show that the disk mass is strongly peaked at 1 R
⊙ (modulo the unknown inclination), and the disk eccentricity decreases from a value of 0.44 at the inner edge, to nearly zero at the outer edge. This eccentricity profile is exactly what one expects if the disk is in a global eccentric mode, precessing rigidly under general relativity and gas pressure. The precession period is about two decades. We infer that the mass of the gas disk is roughly equivalent to that of a 50 km rocky body, while the mass of the accompanying dust disk is likely insignificant. The disk eccentricity confirms an origin in tidal disruption, while the short disk diffusion time suggests that the disruption event happened a few centuries ago. Moreover, we argue that the initial orbit for the disrupted body, and that of its putative planetary perturber, fall within an astronomical unit around the white dwarf. The total mass of the source population is likely orders of magnitude more massive than our own Asteroid belt and does not seem to exist around main-sequence stars.

Abstract
We present the results from the first two years of the Planet Hunters Next Generation Transit Survey (NGTS) citizen science project, which searches for transiting planet candidates in data from the NGTS by enlisting the help of members of the general public. Over 8000 registered volunteers reviewed 138,198 light curves from the NGTS Public Data Releases 1 and 2. We utilize a user weighting scheme to combine the classifications of multiple users to identify the most promising planet candidates not initially discovered by the NGTS team. We highlight the five most interesting planet candidates detected through this search, which are all candidate short-period giant planets. This includes the TIC-165227846 system that, if confirmed, would be the lowest-mass star to host a close-in giant planet. We assess the detection efficiency of the project by determining the number of confirmed planets from the NASA Exoplanet Archive and TESS Objects of Interest (TOIs) successfully recovered by this search and find that 74% of confirmed planets and 63% of TOIs detected by NGTS are recovered by the Planet Hunters NGTS project. The identification of new planet candidates shows that the citizen science approach can provide a complementary method to the detection of exoplanets with ground-based surveys such as NGTS.
High-precision Atmospheric Characterization of a Y Dwarf with JWST NIRSpec G395H Spectroscopy: Isotopologue, C/O Ratio, Metallicity, and the Abundances of Six Molecular Species

Abstract
The launch of the James Webb Space Telescope (JWST) marks a pivotal moment for precise atmospheric characterization of Y dwarfs, the coldest brown dwarf spectral type. In this study, we leverage moderate spectral resolution observations (R ∼ 2700) with the G395H grating of the Near-Infrared Spectrograph (NIRSpec) on board JWST to characterize the nearby (9.9 pc) Y dwarf WISEPA J182831.08+265037.8. With the NIRSpec G395H 2.88–5.12 μm spectrum, we measure the abundances of CO, CO2, CH4, H2S, NH3, and H2O, which are the major carbon-, nitrogen-, oxygen-, and sulfur-bearing species in the atmosphere. Based on the retrieved volume mixing ratios with the atmospheric retrieval framework CHIMERA, we report that the C/O ratio is 0.45 ± 0.01, close to the solar C/O value of 0.458, and the metallicity is +0.30 ± 0.02 dex. Comparison between the retrieval results and the forward modeling results suggests that the model bias for C/O and metallicity could be as high as 0.03 and 0.97 dex, respectively. We also report a lower limit of the 12CO/13CO ratio of >40, being consistent with the nominal solar value of 90. Our results highlight the potential for JWST to measure the C/O ratios down to percent-level precision and characterize isotopologues of cold planetary atmospheres similar to WISE 1828.
Wide-spectral-band Nuller Insensitive to Finite Stellar Angular Diameter with a One-dimensional Diffraction-limited Coronagraph
Authors: Itoh Satoshi , Matsuo Taro , Tamura Motohide 
Published: April 2024

Abstract
Potentially habitable planets around nearby stars less massive than solar-type stars could join targets of the spectroscopy of the planetary reflected light with future space telescopes. However, the orbits of most of these planets occur near the diffraction limit for 6 m diameter telescopes. Thus, while securing contrast-mitigation ability under a broad spectral bandwidth and a finite stellar angular diameter, we must maintain planetary throughput even at the diffraction-limited angles to be able to reduce the effect of the photon noise within a reasonable observation time. A one-dimensional diffraction-limited coronagraph (1DDLC) observes planets near the diffraction limit with undistorted point spread functions but has a finite-stellar diameter problem in wideband use. This study presents a method for wide-spectral-band nulling insensitive to stellar-angular-diameter by adding a fiber nulling with a Lyot-plane phase mask to the 1DDLC. Designing the pattern of the Lyot-plane mask function focuses on the parity of the amplitude spread function of light. Our numerical simulation shows that the planetary throughput (including the fiber-coupling efficiency) can reach about 11% for about 1.35-λ/D planetary separation almost independently of the spectral bandwidth. The simulation also shows the raw contrast of about 4 × 10−8 (the spectral bandwidth of 25%) and 5 × 10−10 (the spectral bandwidth of 10%) for 3 × 10−2
λ/D stellar angular diameter. The planetary throughput depends on the planetary azimuthal angle, which may degrade the exploration efficiency compared to an isotropic throughput but is partially offset the wide spectral band.

Abstract
In this paper, we present the Heavy Metal Survey, which obtained ultradeep medium-resolution spectra of 21 massive quiescent galaxies at 1.3 < z < 2.3 with Keck/LRIS and MOSFIRE. With integration times of up to 16 hr per band per galaxy, we observe numerous Balmer and metal absorption lines in atmospheric windows. We successfully derive spectroscopic redshifts for all 21 galaxies, and for 19 we also measure stellar velocity dispersions (σ

v
), ages, and elemental abundances, as detailed in an accompanying paper. Except for one emission-line active galactic nucleus, all galaxies are confirmed as quiescent through their faint or absent Hα emission and evolved stellar spectra. For most galaxies exhibiting faint Hα, elevated [N ii]/Hα suggests a non-star-forming origin. We calculate dynamical masses (M
dyn) by combining σ

v
with structural parameters obtained from the Hubble Space Telescope COSMOS(-DASH) survey and compare them with stellar masses (M
*) derived using spectrophotometric modeling, considering various assumptions. For a fixed initial mass function (IMF), we observe a strong correlation between M
dyn/M
* and σ

v
. This correlation may suggest that a varying IMF, with high-σ

v
galaxies being more bottom heavy, was already in place at z ∼ 2. When implementing the σ

v
-dependent IMF found in the cores of nearby early-type galaxies and correcting for biases in our stellar mass and size measurements, we find a low scatter in M
dyn/M
* of 0.14 dex. However, these assumptions result in unphysical stellar masses, which exceed the dynamical masses by 34%. This tension suggests that distant quiescent galaxies do not simply grow inside-out into today’s massive early-type galaxies and the evolution is more complicated.

Abstract
The small-scale linear information in galaxy samples typically lost during nonlinear growth can be restored to a certain level by the density field reconstruction, which has been demonstrated for improving the precision of the baryon acoustic oscillation (BAO) measurements. As proposed in the literature, a joint analysis of the power spectrum before and after the reconstruction enables an efficient extraction of information carried by high-order statistics. However, the statistics of the postreconstruction density field are difficult to model. In this work, we circumvent this issue by developing an accurate emulator for the prereconstructed, postreconstructed, and cross-power spectra (

Abstract
The Hercules ultrafaint dwarf galaxy (UFD) has long been hypothesized to be tidally disrupting, yet no conclusive evidence has been found for tidal disruption owing partly to difficulties in identifying Hercules member stars. In this work, we present a homogeneous reanalysis of new and existing observations of Hercules, including the detection of a new potential member star located ∼1° (∼1.7 kpc) west of the center of the system. In addition to measuring the line-of-sight velocity gradient, we compare predictions from dynamical models of stream formation to these observations. We report an updated velocity dispersion measurement based on 28 stars,

km s−1 kpc along the major axis of Hercules, consistent with zero within 1σ. Our dynamical models of stream formation, on the other hand, can reproduce the morphology of the Hercules UFD, specifically the misalignment between the elongation and the orbital motion direction. Additionally, these dynamical models indicate that any radial velocity gradient from tidal disruption would be too small,

km s−1 kpc, to be detectable with current sample sizes. Combined with our analysis of the tidal radius evolution of the system as a function of its orbital phase, we argue that it is likely that Hercules is indeed currently undergoing tidal disruption in its extended stellar halo with a line-of-sight velocity gradient too small to be detected with current observational data sets.
