description: We present observations of the type-2 Seyfert NGC7172 obtained with the medium-resolution spectrometer (MRS) of the Mid-Infrared Instrument (MIRI) on board of the JWST. This galaxy hosts one of the lowest ionised gas mass outflow rates (Mout~0.005 M/yr) in a sample of six AGN with similar bolometric luminosities (log Lbol~44erg/s) within the Galactic Activity, Torus and Outflow Survey (GATOS). We aim to understand the properties of the ionised gas outflow, mainly using the emission lines from the neon transitions, that cover a broad range of ionisation potentials (IP) from ~20 eV to ~130 eV. We applied parametric and non-parametric methods to characterise the line emission and kinematics. The low excitation lines (IP<25eV, e.g.[NeII]) trace the rotating disc emission. The high excitation lines (IP>90eV, e.g.[NeV]), which are likely photoionised exclusively by the AGN, are expanding in the direction nearly perpendicular to the disc of the galaxy, with maximum projected velocities of ~350-500 km/s. In particular, [NeV] and [NeVI] lines reveal a biconical ionised gas outflow emerging N-S from the nuclear region, extending at least ~2.5"N and 3.8"S (projected distance of ~450 and 680 pc). Most of the emission arising in the northern part of the cone was not previously detected due to obscuration. Given the almost face-on orientation of the outflow and the almost edge-on orientation of the galaxy, NGC7172 may be a case of weak coupling. Nevertheless, we found evidence for positive feedback in two distinct outflowing clumps at projected distances of 3.1" and 4.3" (i.e. ~560 and 780 pc) SW from the AGN. We estimated a star formation rate in these regions using the [NeII] and [NeIII] luminosities of 0.08 M/yr, that is ~10% of that found in the circumnuclear ring. The star formation activity might have been triggered by the interaction between the ionised gas outflow and the ISM of the galaxy.

description: Automated detection of contraband items in X-ray images can significantly increase public safety, by enhancing the productivity and alleviating the mental load of security officers in airports, subways, customs/post offices, etc. The large volume and high throughput of passengers, mailed parcels, etc., during rush hours practically make it a Big Data problem. Modern computer vision algorithms relying on Deep Neural Networks (DNNs) have proven capable of undertaking this task even under resource-constrained and embedded execution scenarios, e.g., as is the case with fast, single-stage object detectors. However, no comparative experimental assessment of the various relevant DNN components/methods has been performed under a common evaluation protocol, which means that reliable cross-method comparisons are missing. This paper presents exactly such a comparative assessment, utilizing a public relevant dataset and a well-defined methodology for selecting the specific DNN components/modules that are being evaluated. The results indicate the superiority of Transformer detectors, the obsolete nature of auxiliary neural modules that have been developed in the past few years for security applications and the efficiency of the CSP-DarkNet backbone CNN.

description: The first LIGO-Virgo detections have confirmed the existence of massive black holes (BHs), with mass $30-40$ M$_\odot$. Such BHs might originate from massive metal-poor stars ($Z<0.3$ Z$_\odot$) or from gravitational instabilities in the early Universe. The formation channels of merging BHs are still poorly constrained. The measure of mass, spin and redshift distribution of merging BHs will give us fundamental clues to distinguish between different models. Also, a better understanding of several astrophysical processes (e.g. common envelope, core-collapse supernovae, and dynamical evolution of BHs) is decisive, to shed light on the formation channels of merging BHs.

description: Three-dimensional (3D) radiative magnetohydrodynamics (MHD) simulations are the only way to model stellar atmospheres without any ad hoc parameterisations. Several 3D radiative MHD codes have achieved good quantitative agreement with observables for our Sun. We aim to validate the most up-to-date version of the MURaM code against well established quiet Sun measurements, in particular spatially averaged measurements that are relevant for stellar studies. This validation extends the number of solar observables that MURaM can reproduce with high precision. It is also an essential condition for using MURaM to accurately calculate spectra of other cool stars. We simulate the solar upper convection zone and photosphere harbouring a small-scale-dynamo. Using time series of 3D snapshots we calculate the spectral irradiance, limb darkening and selected spectral lines, which we compare to observations. The computed observables agree well with the observations, in particular the limb darkening of the quiet Sun is reproduced remarkably well.

description: A first look is taken at the NIRSpec 1-5 $μ$m observations from JWST program 1591 that targets 7 objects along the low-mass stellar life cycle with PAH emission. Spectra extracted from a 1.5$^{\prime\prime}$ radius sized circular aperture are explored, showing a wealth of features, including the 3 $μ$m PAH complex, the PAH-continuum, and atomic and molecular emission lines from HI, He, H$_{\rm 2}$, and other species. CO$_{\rm 2}$- and H$_{\rm 2}$O-ice absorption and CO emission is also seen. Focusing on the bright-PDR position in M17, the PAH CH stretch falls at 3.29 $μ$m (FWHM=0.04 $μ$m). Signs of its 1.68 $μ$m overtone are confused by line emission in all targets. Multi-component decomposition reveals a possible aliphatic deuterated PAH feature centered at 4.65 $μ$m (FWHM=0.02 $μ$m), giving [D/H]$_{\rm alip.}$=31$\pm$12.7%. However, there is little sign of its aromatic counterpart between 4.36-4.43 $μ$m. There is also little sign of PAH-nitrile emission between 4.34-4.39 $μ$m. A PAH continuum rises from $\sim$1 to 3.2 $μ$m, after which it jumps by about a factor of 2.5 at 3.6 $μ$m, with bumps at 3.8, 4.04, and 4.34 $μ$m adding structure. The CO$_{\rm 2}$ absorption band in M17 is matched with 10:1 H$_{\rm 2}$O:CO$_{\rm 2}$ ice at 10 K. The $v$=0 pure rotational molecular hydrogen population diagram reveals $>$2200 K UV-pumped gas. The hydrogen Pfund series runs from levels 10 to $>$30. Considering Br$α$/Br$β$=0.381$\pm$0.01966 and Case B recombination results in A$_{\rm V}{\simeq}$8. CO emission in IRAS21282+5050 originates from 258 K gas. In-depth spectral-spatial analysis of all features and targets are planned for a series of forthcoming papers.

description: In general relativity, the use of conformal transformation is ubiquitous and leads to two different frames of reference, known as the Jordan and the Einstein frames. Typically, the transformation from the Jordan frame to the Einstein frame involves introducing an additional scalar degree of freedom, often already present in the theory. We will show that at the quantum level, owing to this extra scalar degree of freedom these two frames exhibit subtle differences that the entanglement between two massive objects can probe.

description: We present K'-band galaxy counts in the magnitude range $13 < K' < 20$, obtained from two independent surveys near the South Galactic Pole, covering an area of $\sim 40 arcmin^2$ and $\sim 170 arcmin^2$, including $\sim 200$ and $\sim 1000$ objects respectively up to a magnitude limit $K' \sim 20.0$ and $K'\sim 19.0$. At magnitudes $K > 18.5$ we surveyed an area more than 7 times wider that covered by previous K-band surveys. Our counts are quite in good agreement with those in the literature at magnitudes brighter than $K \sim 17$, while are systematically lower at fainter magnitudes. We confirm a change in the slope of the $dlogN/dm$ relation at $K' \sim 17$ from 0.57 to 0.35, but do not find the bump shown by other K-band surveys in the magnitude range $16 < K < 20$. Furthermore 10% of the galaxies brighter than $K' \sim 18$ have $B-K'<3$. We suggest that these blue objects represent a population of sub-$L^*$ nearby evolving galaxies.

description: Ring galaxies are fascinating laboratories: a catastrophic impact between two galaxies (one not much smaller than the other) has produced fireworks especially in the larger one, when hit roughly perpendicularly to the plane. We analyze the point sources, produced by the starburst episode following the impact, in the rings of seven galaxies and determine their X-ray luminosity function (XLF). In total we detect 63 sources, of which 50 have luminosity L$_X \geq 10^{39}$ erg s$^{-1}$, classifying them as ultra luminous X-ray sources (ULXs). We find that the total XLF is not significantly different from XLFs derived for other kinds of galaxies, with a tendency of having a larger fraction of high X-ray luminosity objects. Both the total number of ULXs and the number of ULXs per unit star formation rate are found in the upper envelope of the more normal galaxies distribution. Further analysis would be needed to address the issue of the nature of the compact component in the binary system.

description: The Minimally Entangled Typical Thermal States (METTS) are an ensemble of pure states, equivalent to the Gibbs thermal state, that can be efficiently represented by tensor networks. In this article, we use the Projected Entangled Pair States (PEPS) ansatz as to represent METTS on a two-dimensional (2D) lattice. While Matrix Product States (MPS) are less efficient for 2D systems due to their complexity growing exponentially with the lattice size, PEPS provide a more tractable approach. To substantiate the prowess of PEPS in modeling METTS (dubbed as PEPS-METTS), we benchmark it against the purification method for the 2D quantum Ising model at its critical temperature. Our analysis reveals that PEPS-METTS achieves accurate long-range correlations with significantly lower bond dimensions. We further corroborate this finding in the 2D Fermi Hubbard model at half-filling. At a technical level, we introduce an efficient \textit{zipper} method to obtain PEPS boundary matrix product states needed to compute expectation values. The imaginary time evolution is performed with the neighbourhood tensor update.

A Hypothesis on Production of Tachyons

Publisher: name: arXiv
Year: 1999
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: An exact solution of the Einstein--Maxwell equations yields a general relativistic picture of the tachyonic phenomenon, suggesting a hypothesis on the tachyon creation. The hypothesis says that the tachyon is produced when a neutral and very heavy (over 75 GeV/c^2) subatomic particle is placed in electric and magnetic fields that are perpendicular, very strong (over 6.9 x 10^17 esu/cm^2 or oersted), and the squared ratio of their strength lies in the interval (1,5]. Such conditions can occur when nonpositive subatomic particles of high energy strike atomic nuclei other than the proton. The kinematical relations for the produced tachyon are given. Previous searches for tachyons in air showers and some possible causes of their negative results are discussed. Experiments with the use of the strongest colliders and improvements in the air shower experiments are suggested. An unfortunate terminology is also discussed.

description: We present quasiparticle (QP) energies from fully self-consistent $GW$ (sc$GW$) calculations for a set of prototypical semiconductors and insulators within the framework of the projector-augmented wave methodology. To obtain converged results, both finite basis-set corrections and $k$-point corrections are included, and a simple procedure is suggested to deal with the singularity of the Coulomb kernel in the long-wavelength limit, the so called head correction. It is shown that the inclusion of the head corrections in the sc$GW$ calculations is critical to obtain accurate QP energies with a reasonable $k$-point set. We first validate our implementation by presenting detailed results for the selected case of diamond, and then we discuss the converged QP energies, in particular the band gaps, for a set of gapped compounds and compare them to single-shot $G_0W_0$, QP self-consistent $GW$, and previously available sc$GW$ results as well as experimental results.

Wirkung in der wirtschaftlichen Sozialhilfe : Wirkungen, Wirkfaktoren, Adressat:innen, Sozialarbeitende – was wirkt unter welchen Bedingungen bei wem?

Year: 2024
Subjects: 361: Sozialarbeit und Sozialhilfe

description: Wirkung wird in der Sozialen Arbeit einerseits kontrovers diskutiert. Anderseits ist der Nachweis von Wirkung und Wirkfaktoren in der Sozialen Arbeit wenig fortgeschritten. Aus diesen Gründen fragt die Arbeit, inwiefern die Einschätzungen von Adressat:innen und Sozialarbeitenden bezüglich der wirtschaftlichen Sozialhilfe übereinstimmen oder nicht und was allenfalls abweichende Faktoren sind.
Es wurde ein Wirkungsmodell entworfen, welches Wirkfaktoren, erwünschte und unerwünschte Wirkung abbildet. Dieses wurde mittels einer quantitativen Untersuchung einer empirischen Analyse unterzogen.

Es zeigt sich, dass Sozialarbeitende und Adressat:innen in ihren Einschätzungen bezüglich Wirkung und Wirkfaktoren nur wenig voneinander abweichen, jedoch ergeben sich in den jeweiligen Perspektiven verschiedene Zusammenhänge zwischen Wirkfaktoren und Wirkungen.
Zwei Haupterkenntnisse sind hervorzuheben:

- Partizipation ist sowohl bei den Adressat:innen wie bei den Sozialarbeitenden eine positive Einflussgrösse.

- Die gesellschaftliche Einstellung zu Armut wirkt in vielerlei Hinsicht negativ auf die Adressat:innen ein. Die Wirkung der wirtschaftlichen Sozialhilfe wird dadurch entsprechend beeinflusst.

Es ist empfohlen, dass Sozialdienste Wirkungsmodelle erarbeiten bei denen die Partizipation als Wirkung definiert und die gesellschaftliche Einstellung zu Armut mitgedacht wird.
Bei Evaluationen ist darauf zu achten, dass die Sichtweise der Adressat:innen und Sozialarbeitenden abgeholt wird, da sie sich in der Deutung von Wirkung zu ergänzen scheinen.

description: Die vorliegende Masterarbeit untersucht das Vertrauen von Sozialarbeitenden im Kindesschutz in KI-gestützte Entscheidungshilfen und die Bereitschaft, entsprechende Tools in den Arbeitsalltag zu integrieren. Im Rahmen einer Online-Umfrage nahmen 204 Berufsbeistandspersonen aus der Deutschschweiz teil. Die Untersuchung basiert auf dem modifizierten Technologieakzeptanzmodell (TAM) und überprüft fünf Hypothesen, die sich auf Faktoren wie Invasivität, prädiktive Validität und wissenschaftliches Wissen beziehen.
Das Design der Umfrage verwendete ein multifaktorielles, experimentelles Vignettendesign, bei dem den Teilnehmenden verschiedene hypothetische Szenarien zugewiesen wurden. Diese Szenarien variierten die Hauptfaktoren, um deren Einfluss auf das Vertrauen in KI-gestützte Entscheidungshilfen zu messen. Die beiden Fallbeispiele enthielten unterschiedliche fiktive KI-Tools, welche möglicherweise in Zukunft in ähnlicher Form im Kindesschutz eingesetzt werden könnten. Dabei handelte es sich einerseits um ein «Risikomodell» (KIBAT) und um ein «Chancenmodell » (WIEW). Die Ergebnisse zeigen, dass eine geringere Invasivität von Einschätzungen und die Wahrnehmung von hoher prädiktiver Validität (Treffsicherheit) von Tools das Vertrauen in die KI-gestützten Empfehlungen erhöhen, während die Wahrnehmung von wissenschaftlichem Wissen innerhalb der Empfehlungen allein keinen Einfluss auf das Vertrauen in KI-gestützte Tools hat. Zudem korreliert eine positive Einstellung gegenüber KI-Technologien stark mit einem höheren Vertrauen. Ein höheres Vertrauen in die Tools beeinflusst ausserdem die Bereitschaft, die Tools im Arbeitsalltag zu integrieren.
Die Thesis hebt hervor, dass eine sorgfältige Einführung und Schulung, die Transparenz der Funktionsweise und die ethische Verantwortlichkeit entscheidend für das Vertrauen und eine erfolgreiche Implementierung von KI in der Sozialen Arbeit sind. Durch die Kombination menschlicher Expertise und technologischer Unterstützung können objektivere und fundiertere Entscheidungen getroffen werden, was die Handlungssicherheit und die Qualität im Kindesschutz verbessert. Die Studie betont die Notwendigkeit, KI als ergänzendes Werkzeug zu betrachten, das die professionelle Urteilsfähigkeit stärkt, ohne sie zu ersetzen. Es wird empfohlen, die Soziale Arbeit möglicherweise neu zu denken, um den bestmöglichen Einsatz der Technologie zu gewährleisten und die professionellen Standards zu erhalten und zu verbessern.

description: A new spinning particle with a definite sign of the energy is defined on spacelike hypersurfaces after a critical discussion of the standard spinning particles. They are the pseudoclassical basis of the positive energy $({1\over 2},0)$ [or negative energy $(0,{1\over 2})$] parts of the $({1\over 2},{1\over 2})$ solutions of the Dirac equation. The study of the isolated system of N such spinning charged particles plus the electromagnetic field leads to their description in the rest-frame Wigner-covariant instant form of dynamics on the Wigner hyperplanes orthogonal to the total 4-momentum of the isolated system (when it is timelike). We find that on such hyperplanes these spinning particles have a nonminimal coupling only of the type "spin-magnetic field" like the nonrelativistic Pauli particles to which they tend in the nonrelativistic limit. The Lienard-Wiechert potentials associated with these charged spinning particles are found. Then, a comment on how to quantize the spinning particles respecting their fibered structure describing the spin structure is done.

description: In the memory of Italians the figure of Gabriele d’Annunzio is veiled and confused by time, muted by historical events and the evolution of human sensibility. However, the Vittoriale in Gardone, last residence of the poet, and still wonderfully intact and vital, signals with inalterable resistence the interpretation of a dream, that of conceiving life as a work of art and architecture as guardian of its places, those of a sublime dwelling which transcends eras, thoughts and oblivion.

description: In this paper, we present the discovery of a dual AGN in a $\sim$11:1 minor merger between the galaxy SDSS J125417.98+274004.6 and its unnamed dwarf satellite. We calculated stellar masses of the primary and secondary galaxy to be 2.5$\times$10$^{10}$M$_{\odot}$ and 2.2$\times$10$^{9}$M$_{\odot}$, respectively. We used archival Chandra X-ray observations to assess the presence of AGN. We found that both AGN have comparable luminosities of $\sim$2$\times$10$^{42}$ erg s$^{-1}$, with the secondary AGN being more likely to be the dominant one. The galaxies are in the early stages of the merger and are connected by a tidal bridge. Previous works suggest that the secondary AGN should experience a brief but intensive period of Eddington-limit approaching accretion during the early stages of the merger. During the merger, the secondary black hole can increase its mass by a factor of ten. SDSS J125417.98+274004.6 is the first known dual AGN in an early-stage minor merger with a comparably or more luminous secondary AGN. As such, it will be of great value for future studies of merger-triggered accretion and black hole growth mechanisms.

description: From the etymological meaning of the term image and from its definitions in ancient times, the essay proposes a critical interpretation of the iconographical value of some ancient paintings from the area around mount Vesuvius. In particular the work focuses on the philological and digital reconstruction, carried out following iconographic and bibliographic references and the few remaining pictorial traces, of the cycle of frescos that decorated the cylindrical walls of the Frigidarium at the Stabian baths (Pompeii). These images, buried by the eruption of mount Vesuvius in the year 79 A.C., are presented here in their original configuration, through a projection immersed in their own environment.

description: The first all-sky maps of the diffuse emission of high ionization lines observed in X-rays by SRG/eROSITA, provide an excellent probe for the study of the warm-hot phase (T~10^6 K) of the circumgalactic medium (CGM) of the Milky Way (MW). In this work we analyse the O VIII line detected in the first eROSITA All-Sky Survey data (eRASS1). We fit a sky map made in a narrow energy bin around this line, with physical emission models embedded in a 3D geometry to constrain the density distribution of the warm-hot gas around our Galaxy, with a focus on mid and high (absolute) Galactic latitudes. By masking out the eROSITA bubbles and other bright extended foreground sources, we find that an oblate geometry of the warm-hot gas (T~0.15-0.17 keV), flattened around the Galactic disk with scale height z_h~1-3 kpc, best describes the eRASS1 O VIII map, with most of the observed emission resulting to be produced within a few kpc from the Sun. The additional presence of a large scale warm-hot spherical halo, while providing a minor contribute to the X-ray emission, accounts for the high O VII absorption column densities detected with XMM-Newton, as well as most of the baryon budget of the CGM of the MW. The eROSITA data carry the largest amount of information and detail of O VIII CGM intensities to date, allowing for a significant reduction of the statistical uncertainties of the inferred physical parameters.

Ineguaglianze e povertà delle donne nella Cina dello sviluppo economico

description: Since 1978, the poor population in China has shrunk by almost 500 million and the proportion of malnourished people, about 25% in 1992, has fallen to 10% in 2012-2014. However, not everyone benefited from this extraordinary economic performance. In saying “let some people get rich before the others”, the post-Mao leadership promoted a model of development that accepted both the disparities between different groups and the marginalization of the most vulnerable people. Among the latter, women are the majority because the programs implemented to fight poverty underestimated gender specificities.

description: Brussels, the visible symbol of unity in diversity is a "temple" of lobbying. Its functioning institutional structure can be recognized as agora, same as a game field for pressure groups. One sentence describes it perfectly: lobby or not to be - lobitur ergo sum. In ths book, author characterizes the phenomenon at supranational level, discusses concepts of lobbying in terms of their evolution and meaning. Reveals the influence of lobbying to the institutional and decision-making process of the Commission, the European Parliament, the European Council and the Council of the European Union to present complex interactions of lobbying and decision-making sphere. In the context of the legal framework for lobbying activities also analyse the jurisduction of the Court of Justice of the European Union on the aspect of access to documents of the EU institutions. Looking through the prism of economic interests representation, indicates the possibility of effective influence on the legislative process. Important are reflections on the direct and indirect methods and forms of activities of interest groups at the Brussels Forum, as well as litigation strategies and sharing of information using the possibilities offered by the Internet. These are the essential elements to highlight the professional rules of preparing effective lobbying strategies possible to implement at the EU level.
Kes 73: A Young Supernova Remnant with an X-ray Bright, Radio-quiet Central Source

description: We clarify the nature of the small-diameter supernova remnant (SNR) Kes 73 and its central compact source, 1E 1841-045, using X-ray data acquired with the ASCA Observatory. We introduce a spatio-spectral decomposition technique necessary to disentangle the ASCA spectrum of the compact source from the barely resolved shell-type remnant. The source spectrum (1 - 8 keV) is characterized by an absorbed power-law with a photon index ~ 3.4 and N_H ~ 3.0E22 cm^-2, possibly non-thermal in nature. This bright X-ray source is likely a slowly spinning pulsar, whose detection is reported in our companion paper (Vasisht & Gotthelf 1997). The SNR spectrum is characteristic of a thermal plasma, with kT ~ 0.7 keV, and emission lines typical of a young remnants. The element Mg and possibly O and Ne are found to be over-abundant, qualitatively suggesting an origin from a massive progenitor. We find that Kes 73 is a young (~ 2000 yr) type II/Ib SNR containing a neutron star pulsar spinning anomalously slow for its age. Kes 73 is yet another member of a growing class of SNRs containing radio-quiet compact sources with a hard spectral signature.

Women of the mines: apartheid and post-apartheid lived realities of South African women
Creators: name: Benya, Asanda
Publisher: name: Storia delle Donne
Year: 2018

description: Drawing from the apartheid and post-apartheid context this paper demonstrates how the poverty in the mines of South Africa, which disproportionally affects women, is a deliberate construction. The paper mainly draws from women who have links with and work in the mines. The first section deals with the historical exclusion of women from mining. I link this exclusion to the migrant labour system and incredibly low wages paid to husbands who were the preferred cheap labour in the mines. I not only locate this in history, but I also draw extensively from the current experiences of women who work in the mines. I argue that not only was apartheid at the heart of the construction of mining women’s poverty, but even in post-apartheid South African women continue to suffer the brunt of the laws that are disguised as having their best interest at heart when in fact women in the mines are prejudiced by these laws. The data I use was collected in several research phases from 2008 until 2015. For almost eleven months, between 2011 and 2012, I worked and lived in the mines. To get at the in-depth and everyday practices I used participant observation, life histories, formal interviews, focus group discussions and relied on day-to-day conversations.

description: Giant low-surface brightness (GLSB) galaxies are an extreme class of objects with very faint and extended gas-rich disks. Malin 1 is the largest GLSB galaxy known to date, but its formation is still poorly understood. We use VLT/MUSE IFU spectroscopic observations of Malin 1 to reveal, for the first time, the presence of H$α$ emission distributed across numerous regions along its disk, up to radial distances of $\sim$100 kpc. We made an estimate of the dust attenuation using the Balmer decrement and found that Malin 1 has a mean H$α$ attenuation of 0.36 mag. We observe a steep decline in the star formation rate surface density ($Σ_{\rm SFR}$) within the inner 20 kpc, followed by a shallow decline in the extended disk. Similarly, the gas phase metallicity we estimated shows a steep gradient in the inner 20 kpc, followed by a flattening of the metallicity in the extended disk with a relatively high value of $\sim$0.6 $Z_{\odot}$. We found that the normalized abundance gradient of the inner disk is similar to values found in normal galaxies but with an extreme value in the extended disk. A comparison of the star formation rate surface density and gas surface density shows that, unlike normal disk galaxies or other LSBs, Malin 1 exhibits a very low star formation efficiency. Owing to the detection of emission lines over a large part of the disk of Malin 1, this work sheds light on the star formation processes in this unique galaxy, highlighting its extended star-forming disk, dust attenuation, almost flat metallicity distribution in the outer disk, and exceptionally low star-formation efficiency. Our findings contribute to a more detailed understanding of the formation of the giant disk of Malin 1 and also constrain possible proposed scenarios on the nature of GLSB galaxies in general.
