A possibility of DM being multicomponent has a strong implication on resolving decades-long known cosmological problems small scale. In addition to elastic scattering, the model allows for inelastic interactions, which can be characterized by 'velocity kick' parameter. The simplest 2cDM with cross section $0.01\lesssim\sigma/m<1\textrm{ cm}^{2}{ \rm g}^{-1}$ and kick velocity $V_{k}\simeq 100\t...

The Tracking Ultraviolet Set-up (TUS) is the world's first orbital imaging detector of Ultra High Energy Cosmic Rays (UHECR) and it operated in 2016-2017 as part scientific equipment Lomonosov satellite. TUS was developed manufactured a prototype larger project K-EUSO with main purpose testing efficiency method for measuring ultraviolet signal extensive air shower (EAS) Earth's night atmosphere...

The splashback radius, $R_{\rm sp}$, is a physically motivated halo boundary that separates infalling and collapsed matter of haloes. We study sp}$ in the hydrodynamic dark only IllustrisTNG simulations. most commonly adopted signature radius at which radial density profiles are steepest. Therefore, we explicitly optimise our profile fit to slope find this leads $\sim5\%$ larger compared other ...

Both long-duration gamma-ray bursts (LGRBs) from core collapse of massive stars and short-duration GRBs (SGRBs) mergers binary neutron star (BNS) or star--black hole (NSBH) are expected to occur in the accretion disk active galactic nuclei (AGNs). We show that GRB jets embedded migration traps AGN disks promised be choked by dense material. Efficient shock acceleration cosmic rays at reverse is...

We measure the harmonic-space auto-power spectrum of galaxy overdensity in LOFAR Two-metre Sky Survey (LoTSS) First Data Release and its cross correlation with map lensing convergence cosmic microwave background (CMB) from Planck collaboration. report a $\sim5\sigma$ detection cross-correlation. show that combination clustering power CMB cross-correlation allows us to place constraints on high-...

We investigate the nature of an unusually faint member $\epsilon$ Cha Association ($D\sim100$ pc, age $\sim5$ Myr), nearest region star formation $<$8 Myr. This object, 2MASS J11550336-7919147 (2M1155$-$79B), is a wide ($\sim$580 AU) separation, comoving companion to low-mass (M3) J11550485-7919108 (2M1155$-$79A). present near-infrared spectra both components, along with analysis photometry fro...

The gas surface density profile of protoplanetary disks is one the most fundamental physical properties to understand planet formation. However, it challenging determine observationally, because H$_2$ emission cannot be observed in low-temperature regions. We analyzed Atacama Large Millimeter/submillimeter Array (ALMA) archival data \co line toward disk around TW Hya and discovered extremely br...

Thirteen yr observation data of 4FGL J0824.9+3915 with the Large Area Telescope on board Fermi Gamma Ray Space (Fermi/LAT) are analyzed for revisiting whether 4C +39.23B, a compact steep-spectrum (CSS) source closed to flat-spectrum radio quasar (FSRQ) +39.23A in $\gamma$-ray emitting region J0824.9+3915, is emitter. We find that time-integrated emission overwhelmingly dominated by +39.23A. It ...

We describe an experimental effort designing and deploying error-robust single-qubit operations using a cloud-based quantum computer analog-layer programming access. design numerically-optimized pulses that implement target exhibit robustness to various error processes including dephasing noise, instabilities in control amplitudes, crosstalk. Pulse optimization is performed flexible package inc...

We present a low metallicity map of the Milky Way consisting $\sim$111,000 giants with $-3.5 \lesssim$ [Fe/H] $\lesssim -$0.75, based on public photometry from second data release SkyMapper survey. These stars extend out to $\sim$7kpc solar neighborhood and cover main Galactic stellar populations, including thick disk inner halo. Notably, this can reliably differentiate metallicities down $\sim...
