Soprannominato Phoenix, l’esopianeta Tic 365102760 b, in orbita intorno a una gigante rossa, ha stupito gli scienziati con la sua atmosfera “puffy”. A causa dell’intensa radiazione della sua stella, infatti, si pensava che il pianeta fosse ormai ridotto a una nuda roccia. Pubblicata su The Astronomical Journal, non è che l’ultima di una serie di scoperte che sollecitano a ripensare la fine di questi mondi in ambienti estremi
Global cosmological dynamics for the scalar field representation of the modified Chaplygin gas

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: In this paper we investigate the global dynamics for the minimally coupled scalar field representation of the modified Chaplygin gas in the context of flat FLRW cosmology. The tool for doing this is a new set of bounded variables that lead to a regular dynamical system. It is shown that the exact modified Chaplygin gas perfect fluid solution appears as a straight line in the associated phase plane. It is also shown that no other solutions stay close to this solution during their entire temporal evolution, but that there exists an open subset of solutions that stay arbitrarily close during an intermediate time interval, and into the future in the case the scalar field potential exhibits a global minimum.

description: Motivated by the new CDF measurement of the $W$ boson mass reported recently which clearly illustrates a large deviation compared to the Standard Model (SM) prediction. In the present paper, we study the Two-Higgs Doublet Model (2HDM) contributions to $M_W$ and its phenomenological implications in the case where the heavy CP-even $H$ is identified as the observed Higgs boson with a mass of $125$ GeV. Taking into account theoretical and all the available experimental constraints as well as the new CDF measurement, we demonstrate that the 2HDM parameter space can provide a large correction which predicts the W mass close to the new CDF $M_W$ measurement. It is found that $M_{H\pm}=M_A$ is excluded and the splitting of the charged Higgs boson with all other states is positive. We also discuss the consequence on the effective mixing angle $\sin^2θ_{\text{eff}}$ as well as the phenomenological implications on the charged Higgs and CP-odd decays.

description: We report Gemini-North GMOS observations of the inflated hot Jupiter HAT-P-32b during two primary transits. We simultaneously observed two comparison stars and used differential spectro-photometry to produce multi-wavelength light curves. 'White' light curves and 29 'spectral' light curves were extracted for each transit and analysed to refine the system parameters and produce transmission spectra from 520-930nm in ~14nm bins. The light curves contain time-varying white noise as well as time-correlated noise, and we used a Gaussian process model to fit this complex noise model. Common mode corrections derived from the white light curve fits were applied to the spectral light curves which significantly improved our precision, reaching typical uncertainties in the transit depth of ~2x10^-4, corresponding to about half a pressure scale height. The low resolution transmission spectra are consistent with a featureless model, and we can confidently rule out broad features larger than about one scale height. The absence of Na/K wings or prominent TiO/VO features is most easily explained by grey absorption from clouds in the upper atmosphere, masking the spectral features. However, we cannot confidently rule out clear atmosphere models with low abundances (~10^-3 solar) of TiO, VO or even metal hydrides masking the Na and K wings. A smaller scale height or ionisation could also contribute to muted spectral features, but alone are unable to to account for the absence of features reported here.

SN 2005ip: A Luminous Type IIn Supernova Emerging from a Dense Circumstellar Medium as Revealed by X-Ray Observations

description: We report on X-ray spectral evolution of the nearby Type IIn supernova (SN) 2005ip, based on Chandra and Swift observations covering from ~1 to 6 years after the explosion. X-ray spectra in all epochs are well fitted by a thermal emission model with kT > 7 keV. The somewhat high temperature suggests that the X-ray emission mainly arises from the circumstellar medium heated by the forward shock. We find that the spectra taken 2-3 years since the explosion are heavily absorbed N_H ~ 5e22 cm^{-2}, but the absorption gradually decreases to the level of the Galactic absorption N_H ~ 4e20 cm^{-2} at the final epoch. This indicates that the SN went off in a dense circumstellar medium and that the forward shock has overtaken it. The intrinsic X-ray luminosity stays constant until the final epoch when it drops by a factor of ~2. The intrinsic 0.2-10 keV luminosity during the plateau phase is measured to be ~1.5e41 erg/s, ranking SN 2005ip as one of the brightest X-ray SNe. Based on the column density, we derive a lower-limit of a mass-loss rate to be M_dot ~ 0.015 (V_w/100 km/s) M_sun/yr, which roughly agrees with that inferred from the X-ray luminosity, M_dot ~ 0.02 (V_w/100 km/s) M_sun/yr, where V_w is the circumstellar wind speed. Such a high mass-loss rate suggests that the progenitor star had eruptive mass ejections like a luminous blue variable star. The total mass ejected in the eruptive period is estimated to be ~15 M_sun, indicating that the progenitor mass is greater than ~25 M_sun.

Analysis of the data from photoelectric gas polarimeters

description: We review the tools and procedures for the analysis of the data collected by X-ray photoelectric gas polarimeters, like the ones on-board the Imaging X-ray Polarimetry Explorer (IXPE). Although many of such tools are in principle common with polarimeters working at other energy bands, the peculiar characteristics and performance of these devices require a specific approach. We will start from the analysis of the raw data read-out from this kind of instruments, that is, the image of the track of the photoelectron. We will briefly present how such images are processed with highly-specialized algorithms to extract all the information collected by the instrument. These include energy, time of arrival and, possibly, absorption point of the photon, in addition to the initial direction of emission of the photoelectron. The last is the quantity relevant for polarimetry, and we will present different methods to obtain the polarization degree and angle from it. A simple method, used extensively especially during the development phase of X-ray photoelectric gas polarimeters, is based on the construction and fitting of the azimuthal distribution of the photoelectrons. We will discuss that there are several reasons to prefer an analysis based on Stokes parameters, especially when one wants to analyze measurements of real, i.e., not laboratory, sources. These are quantities commonly used at all wavelengths because they are additive, and then operations like background subtraction or the application of calibration are trivial to apply. We will summarize how Stokes parameters can be used to adapt current spectroscopy software based on forward folding fitting to perform spectro-polarimetry. Moreover, we will derive how to properly associate the statistical uncertainty on a polarimetry measurement and the relation with another statistical indicator, which is in the minimum detectable polarization.

description: An array of DEPFET pixels is one of several concepts to implement an active pixel sensor. Similar to PNCCD and SDD detectors, the typically 0.45 mm thick silicon sensor is fully depleted by the principle of sideward depletion. They have furthermore in common to be back-illuminated detectors, which allows for ultra-thin and homogeneous photon entrance windows. This enables relatively high quantum efficiencies at low energies and close to 100% for photon energies between 1 keV and 10 keV. Steering of the DEPFET sensor is enabled by a so-called Switcher ASIC and readout is performed by e.g. a VERITAS ASIC. The configuration enables a readout time of a few microseconds per row. This results in full frame readout times of a few milliseconds for a 512 x 512 pixel array in a rolling shutter mode. The read noise is then typically three electrons equivalent noise charge RMS. DEPFET detectors can be applied in particular for spectroscopy in the energy band from 0.2 keV to 20 keV. For example, an energy resolution of about 130 eV FWHM is achieved at an energy of 6 keV which is close to the theoretical limit given by Fano noise. Pixel sizes of a few tens of microns up to a centimetre are feasible by the DEPFET concept.

description: We study a simple model of dynamic networks, characterized by a set preferred degree, $κ$. Each node with degree $k$ attempts to maintain its $κ$ and will add (cut) a link with probability $w(k;κ)$ ($1-w(k;κ)$). As a starting point, we consider a homogeneous population, where each node has the same $κ$, and examine several forms of $w(k;κ)$, inspired by Fermi-Dirac functions. Using Monte Carlo simulations, we find the degree distribution in steady state. In contrast to the well-known Erdős-Rényi network, our degree distribution is not a Poisson distribution; yet its behavior can be understood by an approximate theory. Next, we introduce a second preferred degree network and couple it to the first by establishing a controllable fraction of inter-group links. For this model, we find both understandable and puzzling features. Generalizing the prediction for the homogeneous population, we are able to explain the total degree distributions well, but not the intra- or inter-group degree distributions. When monitoring the total number of inter-group links, $X$, we find very surprising behavior. $X$ explores almost the full range between its maximum and minimum allowed values, resulting in a flat steady-state distribution, reminiscent of a simple random walk confined between two walls. Both simulation results and analytic approaches will be discussed.

The initial configuration includes a homogeneous magnetic field forming an angle with the direction in which the plasma is perturbed. For each field inclination we compare two simulations, one for the pure MHD case, and one including the ambipolar diffusion in the Ohm's law, otherwise identical. We find that the configuration containing neutral atoms is always unstable. The growth rate of the small-scale modes in the non-linear regime is larger than in the purely MHD case.

description: The detection of quasi-periodic oscillations (QPOs) in the light curves of active galactic nuclei (AGNs) can provide insights into the physics of the super-massive black-holes (SMBHs) powering these systems and could represent a signature of the existence of SMBH binaries, setting fundamental constraints on SMBH evolution in the Universe. The identification of long term QPOs, characterized by periods on the order of several months to years, is particularly challenging and can only be achieved via all-sky monitoring instruments that provide unbiased, continuous light-curves of astrophysical objects. The Fermi-LAT satellite, thanks to its monitoring observing strategy, is an ideal instrument for such a goal. Here, we aim to identify QPOs in the $γ$-ray light-curves of the brightest AGNs within the Fermi-LAT catalog. We analyzed the light curves of the 35 brightest Fermi-LAT AGNs, including data from the beginning of the Fermi mission (August 2008) to April 2021, with energies from 100 MeV to 300 GeV. Two time binnings were investigated, 7 and 30 days. The search for quasi-periodic features was then performed using the continuous wavelet transform. The significance of the result was tested via Monte Carlo simulations of artificial light curves with the same power spectral density and probability distribution function as the original light curves. The significances were then corrected for the look-elsewhere effect and provided as post-trials. We identified 24 quasars with candidate QPOs. Several of our candidates coincide with previous claims in the literature, namely: PKS 0537-441, S5 0716+714, Mrk 421, B2 1520+31, and PKS 2247-131. All our candidates are transient. The most significant multi-year QPO, with a period of about 1100 days, was observed in the quasar S5 1044+71. It is reported here for the first time.

description: Planck data has not found the 'smoking gun' of non-Gaussianity that would have necessitated consideration of inflationary models beyond the simplest canonical single field scenarios. This raises the important question of what these results do imply for more general models, and in particular, multi-field inflation. In this paper we revisit four ways in which two-field scenarios can behave differently from single field models; two-field slow-roll dynamics, curvaton-type behaviour, inflation ending on an inhomogeneous hypersurface and modulated reheating. We study the constraints that Planck data puts on these classes of behaviour, focusing on the latter two which have been least studied in the recent literature. We show that these latter classes are almost equivalent, and extend their previous analyses by accounting for arbitrary evolution of the isocurvature mode which, in particular, places important limits on the Gaussian curvature of the reheating hypersurface. In general, however, we find that Planck bispectrum results only constrain certain regions of parameter space, leading us to conclude that inflation sourced by more than one scalar field remains an important possibility.

description: As the formation of cosmic structure continues to proceed, we observe one of the latest stages of this process in mergers of clusters of galaxies with other clusters, groups, and galaxies. The X-ray emitting hot plasma of these systems can be dramatically affected by these mergers, producing cold and shock fronts, gas sloshing, bulk motions, and turbulence. Combined with numerical simulations, observations of these features can be used to constrain the plasma physics of the hot gas as well as its interaction with high-energy cosmic rays. In this chapter, we review these topics and point forward to what the capabilities of future observatories will reveal.

description: Let Γ(n,p) denote the binomial model of a random triangular group. We show that there exist constants c, C > 0 such that if p <= c/n^2, then a.a.s. Γ(n,p) is free and if p >= C log n/n^2 then a.a.s. Γ(n,p) has Kazhdan's property (T). Furthermore, we show that there exist constants C',c' > 0 such that if C'/n^2 <= p <= c' log n/n^2, then a.a.s. Γ(n,p) is neither free nor has Kazhdan's property (T).

Dall’analisi dei dati della terza release della missione Gaia arriva una nuova ipotesi sull’evoluzione della nostra galassia: secondo i ricercatori del Rensselaer Polytechnic Institute, negli Stati Uniti, l'ultima grande collisione della Via Lattea sarebbe avvenuta almeno cinque miliardi di anni dopo rispetto a quanto ritenuto finora, con l’urto con l’ammasso della Vergine. Lo studio è stato pubblicato su Mnras

La saga del bacino d'acqua liquida nel sottosuolo del Pianeta rosso – esiste o non esiste? – si arricchisce di un nuovo capitolo, firmato questa volta dal “fronte del no”: i tre ricercatori della Cornell University che già avevano contestato la scoperta italiana hanno infatti pubblicato un nuovo studio su Science Advances nel quale mostrano come riflessi analoghi a quelli colti dal radar di Marsis possano essere prodotti da sottili strati di ghiaccio

description: We present results from a Mopra 7mm-wavelength survey that targeted the dense gas-tracing CS(1-0) transition towards the young gamma-ray-bright supernova remnant, RXJ1713.7-3946 (SNR G347.3-0.5). In a hadronic gamma-ray emission scenario, where cosmic ray protons interact with gas to produce the observed gamma-ray emission, the mass of potential cosmic ray target material is an important factor. We summarise newly-discovered dense gas components, towards Cores G and L, and Clumps N1, N2, N3 and T1, which have masses of 1-10^4 solar masses. We argue that these components are not likely to contribute significantly to gamma-ray emission in a hadronic gamma-ray emission scenario. This would be the case if RXJ1713.7-3946 were at either the currently favoured distance of ~1kpc or an alternate distance (as suggested in some previous studies) of ~6kpc. This survey also targeted the shock-tracing SiO molecule. Although no SiO emission corresponding to the RXJ1713.7-3946 shock was observed, vibrationally-excited SiO(1-0) maser emission was discovered towards what may be an evolved star. Observations taken one year apart confirmed a transient nature, since the intensity, line-width and central velocity of SiO(J=1-0,v=1,2) emission varied significantly.

description: We present a percent-level accurate model of the line-of-sight velocity distribution of galaxies around dark matter halos as a function of projected radius and halo mass. The model is developed and tested using synthetic galaxy catalogs generated with the UniverseMachine run on the Multi-Dark Planck 2 N-body simulations. The model decomposes the galaxies around a cluster into three kinematically distinct classes: orbiting, infalling, and interloping galaxies. We demonstrate that: 1) we can statistically distinguish between these three types of galaxies using only projected line-of-sight velocity information; 2) the halo edge radius inferred from the line-of-sight velocity dispersion is an excellent proxy for the three-dimensional halo edge radius; 3) we can accurately recover the full velocity dispersion profile for each of the three populations of galaxies. Importantly, the velocity dispersion profiles of the orbiting and infalling galaxies contain five independent parameters -- three distinct radial scales and two velocity dispersion amplitudes -- each of which is correlated with mass. Thus, the velocity dispersion profile of galaxy clusters has inherent redundancies that allow us to perform nontrivial systematics check from a single data set. We discuss several potential applications of our new model for detecting the edge radius and constraining cosmology and astrophysics using upcoming spectroscopic surveys.

description: We present Herschel photometry and spectroscopy, carried out as part of the Herschel ULIRG survey (HERUS), and a model for the infrared to submillimetre emission of the ultraluminous infrared galaxy IRAS 08572+3915. This source shows one of the deepest known silicate absorption features and no polycyclic aromatic hydrocarbon (PAH) emission. The model suggests that this object is powered by an active galactic nucleus (AGN) with a fairly smooth torus viewed almost edge-on and a very young starburst. According to our model the AGN contributes about 90% of the total luminosity of 1.1 x 10^13 Lo, which is about a factor of five higher than previous estimates. The large correction of the luminosity is due to the anisotropy of the emission of the best fit torus. Similar corrections may be necessary for other local and high-z analogs. This correction implies that IRAS 08572+3915 at a redshift of 0.05835 may be the nearest hyperluminous infrared galaxy and probably the most luminous infrared galaxy in the local (z < 0.2) Universe. IRAS 08572+3915 shows a low ratio of [CII] to IR luminosity (log L_[CII]/L_{IR} < -3.8) and a [OI]63um to [CII]158um line ratio of about 1 that supports the model presented in this letter.

description: We formulate a non-relativistic quantum field theory to model interactions between quantized electromagnetic fields and localized charge-current distributions. The electronic degrees of freedom are encoded in microscopic polarization and magnetization field operators whose moments are identified with the multipole moments of the charge-current distribution. The multipolar Hamiltonian is obtained from the minimal coupling Hamiltonian through a unitary transformation, often referred to as the Power-Zienau-Woolley transformation; we renormalize this Hamiltonian using perturbation theory, the result of which is used to compute the leading-order radiative corrections to the electronic energy levels due to interactions between the electrons and quantum vacuum fluctuations in the electromagnetic field. Our renormalized energy shift constitutes a generalization of the Lamb shift in atomic hydrogen, valid for general localized assemblies of atoms and molecules, possibly with net charge but absent free current. By expanding the fields in a series of multipole moments, our results can be used to study contributions to this energy shift coming from specific multipole moments of arbitrary order.

description: We consider nonlinear effective actions for a spin-2 field, whose `decoupling' limit gives Fierz-Pauli action in D dimensional maximally symmetric spacetime. We find, especially, the effective action for a partially massless field can take a concise geometrical form. The exact solution for time evolution of the background metric in the model using the effective action is also studied.
