Dragon City codes (January 2026)

Codes in Dragon City typically give you free items like food, or helpful boosts to progress faster – whether you’re raising dragons or getting ready for special events. Here’s an updated list of available codes and how to use them.



![Analysis of simulations mirroring the gravitational wave event GW231123, conducted with the NRSur waveform model and assessed through independent detector inference, reveals that divergences between posterior distributions of parameters-including total mass [latex]M_M[/latex], mass ratio [latex]q_q[/latex], luminosity distance [latex]D_{L D}\[/latex], effective inspiral spin [latex]\chi_{eff}[/latex], and precession spin [latex]\chi_p[/latex]-are consistent with expectations for Gaussian noise, with a small percentage of LIGO Livingston and LIGO Hanford pairs exhibiting larger divergences than those observed in GW231123 itself.](https://arxiv.org/html/2601.09678v1/figures_BF/JS_H_L_chip.png)
