We use the \textsc{astraeus} framework, that couples an N-body simulation with a semi-analytic model for galaxy formation and semi-numerical reionization, to quantify star histories (SFHs) of galaxies in first billion years. Exploring four models radiative feedback, we fit SFH each at $z>5$ as $\mathrm{log}(\mathrm{SFR}(z))=-\alpha(1 + z)+\beta$; is deemed stochastic if it deviates from this by...

Primordial black holes (PBHs) may lose mass by Hawking evaporation. For sufficiently small PBHs, they a large portion of their formation today, or evaporate completely if form with M&lt;M_\mathrm{crit}\sim5\times10^{14}~\mathrm{g} M&lt;M<mml:mstyle mat...

We determine the [OIII]$\lambda5007$ equivalent width (EW) distribution of $1.700<\rm{z}<2.274$ rest-frame UV-selected (M$_{\rm{UV}}<-19$) star-forming galaxies in GOODS North and South fields. make use deep HDUV broadband photometry catalogues for selection 3D-HST WFC3/IR grism spectra measurement line properties. The EW allows us to measure abundance extreme emission (EELGs) within this popul...

We present the results of MAXI monitoring and two NuSTAR observations recently discovered faint X-ray transient J1848-015. Analysis light-curve shows that source underwent a rapid flux increase beginning on 2020 December 20, followed by decrease in after only $\sim5$ days. reveal transitioned from bright soft state with unabsorbed, bolometric ($0.1$-$100$ keV) $F=6.9 \pm 0.1 \times 10^{-10}\,\m...

We present a detailed spectral analysis of the joint XMM-Newton and NuSTAR observations active galactic nuclei (AGN) in Seyfert 1.5 Galaxy ESO 362-G18. The broadband ($0.3\mbox{--}79$ keV) spectrum shows presence power-law continuum with soft excess below $2$ keV, iron K$\alpha$ emission ($\sim 6.4$ keV), Compton hump (peaking at $\sim 20$ keV). find that can be modeled by two different possibl...

The CUORE experiment is a large bolometric array searching for the lepton number violating neutrino-less double beta decay ($0\nu\beta\beta$) in isotope $\mathrm{^{130}Te}$. In this work we present latest results on two searches (DBD) of $\mathrm{^{130}Te}$ to first $0^{+}_2$ excited state $\mathrm{^{130}Xe}$: $0\nu\beta\beta$ and Standard Model-allowed two-neutrinos ($2\nu\beta\beta$). Both ar...

Some recent literature has claimed there to be an evolution in galaxies' dust temperatures towards warmer (or colder) spectral energy distributions (SEDs) between low and high redshift. These conclusions are driven by both theoretical models empirical measurement. Such claims sometimes contradict one another prone biases samples or SED fitting techniques. What made direct comparisons difficult ...

We present a Spitzer/IRAC survey of H-faint ($H_{160} \gtrsim 26.4$, $<5\sigma$) sources in 101 lensing cluster fields. Across CANDELS/Wide-like area $\sim$648 arcmin$^2$ (effectively $\sim$221 the source plane), we have securely discovered 53 IRAC Channel-2 band (CH2, 4.5 $\mathrm{\mu m}$; median CH2$=22.46\pm0.11$ AB mag) that lack robust HST/WFC3-IR F160W counterparts. The most remarkable ou...

We have obtained 1 and 3 mm spectral scans of ASXDF1100.053.1 using NOEMA. is an unlensed optically dark millimetre-bright SMG with $K_{\rm AB}>25.7$ ($2\sigma$), which was expected to lie at $z=$5-7 based on its radio-submm photo-$z$. Our data detected line emission due $^{12}$CO($J=$5-4) ($J=$6-5), providing a $z_{\rm CO}= 5.2383\pm0.0005$. Energy-coupled SED modelling indicates properties $L...
